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.
