I don't know. I don't find XLOG_CONTROL_FILE to be a very intuitive proxy for

In sort_inner_and_outer, we create mergejoin join paths by explicitly
sorting both relations on each possible ordering of the available
mergejoin clauses. However, if there are no available mergejoin
clauses, we can skip this process entirely. It seems that this is a
relatively common scenario.
Thanks for the review!

Hi,
Hi,
We can specify more than one privilege type in
"ALTER DEFAULT PRIVILEGES GRANT/REVOKE ON SCHEMAS",
for example,
ALTER DEFAULT PRIVILEGES GRANT USAGE,CREATE ON SCHEMAS TO PUBLIC;
However, the syntax described in the documentation looks to
be allowing only one,
GRANT { USAGE |

As a recent poke on a thread of 2019 has reminded me, the current
situation of partitioned tables with unlogged is kind of weird:

libpq's pqTraceOutputMessage() used to look like this:
case 'Z': /* Ready For Query */
