Bug reference: 17379
Logged by: Greg Rychlewski
Email address: greg.rychlewski@gmail.com
PostgreSQL version: 13.5
Operating system: Mac OS
Description:
When I issue the following multi-command query on a replication connection I
receive a syntax error:
$psql "dbname=postgres replication=database" -c "select 1;select 2;"
ERROR: syntax error
I was curious why this happens, given the documentation at [1] states "In
either physical replication or logical replication walsender mode, only the
simple query protocol can be used."
For comparison, the following query returns the expected result:
$psql "dbname=postgres replication=database" -c "select 1;"
?column?
