Re: PSQL return coder - Mailing list pgsql-hackers
I was avoiding ON_ERROR_STOP because I was using ON_ERROR_ROLLBACK, but have just realised that if I encase my SQL in a transaction then rollback will still happen.
Perfect!

"EXIT STATUS
psql returns 0 to the shell if it finished normally, 1 if a fatal error
of its own (out of memory, file not found) occurs, 2 if the connection
to the server went bad and the session was not interactive, and 3 if an
error occurred in a script and the variable ON_ERROR_STOP was set."
So for a longer script ON_ERROR_STOP might be the ticket (which is
usually a good idea anyways).
