I am following instructions in this link to make mvt file
https://blog.jawg.io/how-to-make-mvt-with-postgis/
When I did the setup and ran generate-tiles.sh , I get the error that bbox function does not exist
ERROR: function bbox(integer, integer, integer) does not exist
LINE 8: BBox(16596, 11273, 15)
If you scroll that page, he is mentioning he is using a helper function and also has given the link.
https://raw.githubusercontent.com/jawg/blog-resources/master/how-to-make-mvt-with-postgis/bbox.sql
I do not have experience with postgis and docker and hence I am stuck.
So my question is, how do I load/install/mount the .sql file so that the script does not produce the error and can call the bbox function ?
Thanks for the comments.
Adding this line to the script file helped.
psql -h /var/run/postgresql -p 5432 -U postgres -d [dbName] -f [scriptsDir]/bbox.sql;
Replace [dbName] with your actual database name and [scriptsDir] where bbox.sql is present.
To verify the port, run this command
sudo lsof -U -a -c postgres

I'm trying to connect to a server's Postgres db through a script. I've ssh-ed into the box and tried
$ psql postgres -U my_username -W #And then entered the password
and get the error:
psql: FATAL: Peer authentication failed for user "my_username"
However, the Rails application running on this server is using these same credentials. I've used ActiveRecord::Base.connection_config in the rails console and used the credentials exactly as they are when trying to use psql. In the rails console, I'm able to query on the database, so I do know the connection is working there.
Is it possible there's a restriction somewhere that's preventing me from connecting through psql? Or is there something else I'm doing wrong?
Try to connect like this:
psql postgres -U my_username -h 127.0.0.1 -W #And then entered the password
Have you tried it like this:
psql --username="postgres"
Another possibility would be to inform more parameters
psql --username="postgres" --host="<ip or host name>" --port="<port, default 5432>" -W <db name>
Good look!
I'm in the process of trying to find out or reset my PostgreSQL password, which is unknown to me, but which I need in order to migrate my database from SQLite3 to PostgreSQL.
I was trying to locate the hba_conf file so in the terminal I entered:
ps aux | grep postgres
and I found that the directory I needed to find was:
/Library/PostgreSQL/9.6/bin/postmaster -D/Library/PostgreSQL/9.6/data
My problem now is that it is not possible to locate this file because it apparently doesn't exist! When I cd to Library I'm unable to go any further because there is no PostgreSQL folder listed.
This is a bit of a dead end for me as I have no idea why PostgreSQL is not there. PSQL came with my version of Rails, and I updated it. When I type: 'psql -V' in the terminal, the answer is 'psql (PostgreSQL) 9.6.3'.
Help would be much appreciated, thanks :-)

The installation procedure creates a user account called postgres that is associated with the default Postgres role. In order to use Postgres, we can log into that account.
You can run the command you'd like with the postgres account directly with sudo
sudo -u postgres psql
This will prompt for the password for the postgres user.
If you don't have the password for this postgres user, follow the below steps:
sudo vim /etc/postgresql/9.3/main/pg_hba.conf
Around the line number 84,85 change that to
# Database administrative login by Unix domain socket
local all all trust
then Restart the PostgreSQL service via SUDO command
sudo /etc/init.d/postgresql restart
Now You can run the command to log in to the postgres account directly with sudo
sudo -u postgres psql
You will be now entered and will See the Postgresql terminal.Once you have successfully logged into postgres, you can change the password by the command
\password
and enter the NEW Password for Postgres default user, After Successfully changing the Password again go to the pg_hba.conf and revert the change to "md5"
Around the line number 84,85 change that now to
# Database administrative login by Unix domain socket
local all all md5
then Restart the PostgreSQL service via SUDO command
sudo /etc/init.d/postgresql restart
now you will be logged in as
psql -U postgres
with your new Password.
Please let me know if you have any Issues.
as we identified your data_dir as /Library/PostgreSQL/9.6/data/ and found configuration files in it, as we identified your postgres cluster is running with pg_ctl: server is running (PID: 88) /Library/PostgreSQL/9.6/bin/postgres "-D/Library/PostgreSQL/9.6/data, in order to reset your password do:
become a postgres user: sudo su - postgres
login locally with psql
reset the password with alter user USERNAME password 'NEW_PASSWORD'
after that you can connect as that user with psql -U USERNAME -h localhost using your new password
I am new to rails.
I want to take backup of pg database from digitalocean to my local machine. How I take dump of that and migrate to my local machine
To use pg_dump,
First, for the target machine(remote machine with database you want to dump), two steps to make the machine receive pg_dump requests:
1.Add or edit the following line in your postgresql.conf :(in my experience, the location maybe /etc/postgresql/9.3/main/postgresql.conf, replace 9.3 with your psql version. If nobody change the file before, you add the line below to the end of the file)
listen_addresses = '*'
2.Add the following line as the first line of file 'pg_hba.conf'. (in my experience, the location like /etc/postgresql/9.3/main/pg_hba.conf) It allows access to all databases for all users with an encrypted password:
# TYPE DATABASEUSER CIDR-ADDRESS METHOD
host all all all md5
After those two steps, type in the terminal:
/etc/init.d/postgresql start
At last, in your local machine, you should figure out the target database's user(or owner) who can read it:
You can achieve this by ssh to connect that machine and step into psql console
sudo su - postgres && psql
and type
\l
to see the db owner.
Finally you can use pg_dump in your local machine to dump the database.Like :
pg_dump -f dump_name -h host_ip -d database_name -U database_user -p 5432 -W
then input the user's password, and wait for the long time for dumping the db.
Hope you make it~
First you need to create backup then download dump from digital ocean and the run these commands on console.
Download dump using SCP.
1-pg_dump dbname > outfile
2-pg_restore --verbose --clean --jobs=4 --disable-triggers --no-acl --no-owner -h localhost -U user_name -d database_name outfile.dump
I was reading a blog post on Percona Monitoring Plugins and how you can somehow monitor a Galera cluster using pmp-check-mysql-status plugin. Below is the link to the blog demonstrating that:
https://www.percona.com/blog/2013/10/31/percona-xtradb-cluster-galera-with-percona-monitoring-plugins/
The commands in this tutorial are run on the command line. I wish to try these commands in a Nagios .cfg file e.g, monitor.cfg. How do i write the services for the commands used in this tutorial?
This was my attempt and i cannot figure out what the best parameters to use for check_command on the service. I am suspecting that where the problem is.
So inside my /etc/nagios3/conf.d/monitor.cfg file, i have the following:
define host{
use generic-host
host_name percona-server
alias percona
address 127.0.0.1
}
## Check for a Primary Cluster
define command{
command_name check_mysql_status
command_line /usr/lib/nagios/plugins/pmp-check-
mysql-status -x wsrep_cluster_status -C == -T str -c non-Primary
}
define service{
use generic-service
hostgroup_name mysql-servers
service_description Cluster
check_command pmp-check-mysql-
status!wsrep_cluster_status!==!str!non-Primary
}
When i run the command Nagios and go to monitor it, i get this message in the Nagios dashboard:
status: UNKNOWN; /usr/lib/nagios/plugins/pmp-check-mysql-status: 31:
shift: can't shift that many
You verified that:
/usr/lib/nagios/plugins/pmp-check-mysql-status -x wsrep_cluster_status -C == -T str -c non-Primary
works fine on command line on the target host? I suspect there's a shell escape issue with the ==
Does this work well for you? /usr/lib64/nagios/plugins/pmp-check-mysql-status -x wsrep_flow_control_paused -w 0.1 -c 0.9
I recently had to reinstall homebrew and postgres and now postgres isn't working with rails.
First when trying to run rails s, I get this:
/Users/lee/.rvm/gems/ruby-1.9.3-p125#achievex/gems/activerecord-3.2.6/lib/active_record/connection_adapters/postgresql_adapter.rb:1206:in `initialize': could not connect to server: Connection refused (PG::Error)
So I try starting postgres and I get this:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
server starting
sh: /usr/local/var/postgres/server.log: No such file or directory
It appears that postgres is running because of this:
ps aux | grep postgreslee 1099 0.3 0.0 2425480 188 s000 R+ 5:48PM 0:00.01 grep postgres
I'm totally at a loss here as to why I can't get it running.
First, ps | grep is in fact pulling your grep out of the process tree. Postgres is not running. This sort of thing happens when the directory to put the log in doesn't exist. So probably you are pointing it at a non-existant directory.
This could happen if you don't have a data directory yet.
Recommendations:
Start by making sure your data directory exists. search for pg_hba.conf and see if it is anywhere on your system. If it is then there is a good chance it is in your data directory (if it is in etc, then look for base/1/PG_VERSION This will be in your data directory one level up from base).
if it exists already change your postgresql.conf to set logging setting appropriately and drop the -l option.
If no data directory exists, use the initdb command to make one.
