Hi,
I've thought about this while working on Pluggable TOAST and 64-bit
TOAST value ID myself. Agree with #2 to seem the best of the above.
There are not so many places where a new header should be included.

Hi, hackers.
psql \copy command can stream data from client host just like the normal
copy command can do on server host. Let's assume we want to stream a
local data file from psql:
pgsql =# \copy tbl from '/tmp/datafile' (format 'text');
If there's error inside the data file, \copy will still

Since a few days ago, the windows/meson task has been spewing messages for each
tap
test:

version 12.
I guess because the image is updated to use meson v1.0.0.

I took another look at the code coverage situation around freezing
following pushing the page-level freezing patch earlier today. I
spotted an issue that I'd missed up until now: certain sanity checks
in heap_prepare_freeze_tuple() call TransactionIdDidCommit() more

Most backend code doesn't actually need the variable-length data types
support (TOAST support) in postgres.h. So I figured we could try to put
it into a separate header file. That makes postgres.h more manageable,
and it avoids including a bunch of complicated unused stuff everywhere.

Hi!
The patch applies with no problem, implements what it declared, CF bot is
happy.
Without patch \dpS shows 0 rows, after applying system objects are shown.
Consider this patch useful, hope it will be committed soon.

Hi!
The patch is implementing what is declared to do. Shell return code is now
accessible is psql var.
Overall code is in a good condition. Applies with no errors on master.
Unfortunately, regression tests are failing on the macOS due to the
different shell output.

Most callers of BufFileRead() want to check whether they read the full

This patch provides additional variants BufFileReadExact() and
