Hi,
While working to address some of Dave's concerns at [1], I encountered the odd
issue of tests failing because postmaster not being allowed to open
pg_control. This did not happen for all tests, but for a lot of tests.
For example, the only output in
pg_upgrade/003_logical_slots/log/003_logic

Hi,
Git on windows defaults to core.autocrlf being enabled. Which means
that a normal git clone will convert all lineendings in text files.
Unfortunately that causes a few tests to fail, at least:
test_json_parser/001_test_json_parser_incremental
test_json_parser/003_test_semantic
pg_bsd_in

Thanks for reviving this patch and for all of your work on it! Eager
aggregation pushdown will be beneficial for my work and I'm hoping to see
it land.
I was playing around with v9 of the patches and was specifically curious
about this previous statement...

Reading through postmaster code, I spotted some refactoring
opportunities to make it slightly more readable.
Currently, when a child process exits, the postmaster first scans
through BackgroundWorkerList to see if it was a bgworker process. If not
found, it scans through the BackendList to see

Hi!
I’m doing another iteration over the patchset.
PgStartLSN = GetXLogInsertRecPtr();
Should this be kind of RecoveryEndPtr? How is it expected to behave on Standby
in HA cluster, which was doing a crash recovery of 1y WALs in a day, then is in
startup for a year as a Hot Standby, and then is

Yeah, apparently --- I get what look like the same diffs with
libxml2 2.13.0 recently supplied by MacPorts. Grumble.
Somebody's going to have to look into that.

Looks like a nice feature to have.
Would it make sense to do something similar to float8? Or, perhaps, some other
types from btree_gist?

1eff8279d4 added memory/disk usage for materialize nodes in EXPLAIN

Hi,
I noticed that ALTER TABLE MERGE PARTITIONS and SPLIT PARTITION commands
always create new partitions in the default tablespace, regardless of
the parent's tablespace. However, the indexes of these new partitions inherit
the tablespaces of their parent indexes. This inconsistency seems odd.
