Yeah, this is a known issue --- the various GRANTs for a specific object
are stored in a single "TOC entry" in the archive, which pg_restore will
send to the server in a single PQexec call, causing them to be effectively
one transaction. The easiest way to deal with it is to not send
pg_restore's output directly to the target server, but feed it through
psql, something like
pg_restore ... | psql [connection parameters]
There's been some discussion of a real fix, but it seems messy.
pg_restore doesn't have a parser that would be adequate to separate
out multiple SQL commands in a TOC entry, and we'd rather not try
to give it one (mainly because of fear of cross-version compatibility
issues).
Okay, thank you. I thought that might be the case: undesirable behavior where the costs outweigh the benefits of fixing. Given that, would it be worth making it more obvious in the pg_restore documentation that pg_restore and its psql output don't always give the same results in the target database?
Best,
