pgsql-server: GUC assign hooks that look at external state in deciding - Mailing list pgsql-committers

Log Message:
-----------
GUC assign hooks that look at external state in deciding whether a
setting is valid must ignore that state and permit the assignment anyway
when source is PGC_S_OVERRIDE.  Otherwise they may disallow a rollback
at transaction abort, which is The Wrong Thing.  Per example from
Michael Fuhr 12-Sep-04.
