Thread: pgsql: Fix timestamp of sent message for write context in logical decod
Fix timestamp of sent message for write context in logical decoding When sending data for logical decoding using the streaming replication protocol via a WAL sender, the timestamp of the sent write message is allocated at the beginning of the message when preparing for the write, and actually computed when the write message is ready to be sent. The timestamp was getting computed after sending the message. This impacts anything using logical decoding, causing for example logical replication to report mostly NULL for last_msg_send_time in pg_stat_subscription. This commit makes sure that the timestamp is computed before sending the message. This is wrong since 5a991ef, so backpatch down to 9.4.
