Say if I want to add a small snip of code in front of the sql script
generated by the pg_dump, to check for something then if the condition
doesn't match, the script terminates right away. (Without actually doing the
restoring stuff that the following large chunk is supposed to do)
Can I do that? And is it a good idea to add arbitrary code to the database
dump sql script?
Thanks!
Wei

Put this at the start of the file to make psql stop if there is an
error:
\set ON_ERROR_STOP 1

No problem if you know what you are doing and/or have good backups :)

You don't have to:
pg_restore mydb.dump | psql --set ON_ERROR_STOP=1
