I understand plpgsql_extra_errors as feature that can be enabled on
developer, test, or preprod environments and can help to identify some
Yes, but the two cases you mentioned above are the "strange" cases, and
you should have to do something extra to allow those, not the other way
I think instead of tying these to extra_*, each GUC should accept a
Why? Why the none, warning, error are not enough? Why are you think so
separate GUC can be better than plpgsql_extra_* ?
The fast setting plpgsql.extra_errors = 'all' can switch to some "safe"
The fast setting plpgsql.extra_warnings = 'all' can helps with
identification, but doesn't break production (or doesn't breaks other tests)
I see two problems with those settings:
1) Neither is enabled by default, so 90% of users have no idea they
exist. Obviously that's an easy enough fix, but...
2) There's no way to incrementally change those values for a single
function. If you've set extra_errors = 'all' globally, a single function
can't say "turn off the too many rows setting for this function".
BTW, while I can see value in being able to change these settings for an
entire function, I think the recommended use should be to only change
them for a specific statement.
