Answer 1

You're database setup is not done correctly, run these commands one by one.
Database setup
Connect to PostgreSQL database
sudo -u postgres psql
Run create database script
\i app/db/explorerpg.sql
\i app/db/updatepg.sql
Run db status commands.
\l view created fabricexplorer database
\d view created tables

Answer 2

Actually it postgres database error ...
In your error its clearly said that the chaincode_id doesnt exit ... so this is the problem .
if you want check what column are existed in the transaction table just follow below step
cd blockchain-explorer/app/persistence/postgreSQL/db
sudo -u postgres psql
\d transactions
check the corresponding column chaincode_id exist or not (it wont exist now ,Thats why you got this error)....
Solution for this type error
If you got any error like this first just go to the blockchain-explorer/app/persistence/postgreSQL/db directory
There you can see two file explorerpg.sql and updatepg.sql open this two file and check the corresponding column if existed on any of this file or not. If not you better to download explorer another version which contain the corresponding columns either of this two file mentioned above.
if existed just run below command on ubuntu
cd blockchain-explorer/app/persistence/postgreSQL/db
sudo -u postgres psql
\i explorerpg.sql
\i updatepg.sql
Once done this command just check the column "chaincode_id " is created or not by
\d transactions
it will list all column just check it on.
if the chaincode_id is exist run the explorer again ....
