I am using postgres 9.5. How can I check if auto commit is on or off? I tried SHOW AUTOCOMMIT where I got ERROR: unrecognized configuration parameter "autocommit" then I did a \set autocommit off and then SHOW AUTOCOMMIT gives me blank output. How can identify if autocommit is on or off? Also can I set it to off while/after the database in created in my sql file?

To tell if AUTOCOMMIT is on or off, issue the set command: $ \set ... AUTOCOMMIT = 'off' ... AUTOCOMMIT is off if a SELECT * FROM LOCKS shows locks from the statement you just ran.
To disable autocommit mode explicitly, use the following statement: SET autocommit=0; After disabling autocommit mode by setting the autocommit variable to zero, changes to transaction-safe tables (such as those for InnoDB or NDB ) are not made permanent immediately.
with pgAdmin 4, you can click the “down” arrow next to the. icon in the query tool to turn off autocommit. with DBeaver, you can click the. icon in the SQL editor to disable autocommit.
If we set auto-commit is off, then we need to write commit to save the transaction into the database. Commit is used to saves the transaction changes into the database. Commit is very important in PostgreSQL to save any changes which the user did.
The default value of commit is ON in PostgreSQL, which means we need not have to execute a commit statement to save the transaction; it will automatically save the transaction into the database. If we set auto-commit is off, then we need to write commit to save the transaction into the database.
One potential surprise for someone familiar with Oracle database 's SQL*Plus when being introduced to PostgreSQL database 's psql may be psql 's default enabling of autocommit. This post provides an overview of psql's handling of autocommit and some related nuances.
Commit: Commit is used in PostgreSQL to save any changes in the database, which the user made. Commit is very important in PostgreSQL to save changes. Work: Work is an optional keyword in a commit. We can use it as “Commit Work”, which means that we save the work into the database.
According to this Dustin Marx article, you can use:
\echo :AUTOCOMMIT
If it's desired to "always" have autocommit disabled, the \set AUTOCOMMIT off meta-command can be added to one's local ~/.psqlrc file. For an even more global setting, this meta-command can be placed in apsqlrc file in the database's system config directory (which can be located using PostgreSQL operating system-level command pg_config --sysconfdir).
