pgsql: Fold FindConversion() into FindConversionByName() and remove ACL - Mailing list pgsql-committers

Log Message:
-----------
Fold FindConversion() into FindConversionByName() and remove ACL check.

All callers of FindConversionByName() already do suitable permissions
checking already apart from this function, but this is not just dead
code removal: the unnecessary permissions check can actually lead to
spurious failures - there's no reason why inability to execute the
underlying function should prohibit renaming the conversion, for example.
(The error messages in these cases were also rather poor:
FindConversion would return InvalidOid, eventually leading to a complaint
that the conversion "did not exist", which was not correct.)
