Subject: pgsql: postgres_fdw: Fix error message for PREPARE TRANSACTION.

Message-ID: <E1iSzQV-0001YN-IA@gemulon.postgresql.org> (raw)
postgres_fdw: Fix error message for PREPARE TRANSACTION.
Currently, postgres_fdw does not support preparing a remote transaction
for two-phase commit even in the case where the remote transaction is
read-only, but the old error message appeared to imply that that was not
supported only if the remote transaction modified remote tables. Change
the message so as to include the case where the remote transaction is
read-only.
Also fix a comment above the message.
Also add a note about the lack of supporting PREPARE TRANSACTION to the
postgres_fdw documentation.
