As I mentioned in [1], checking (struct Port)->ssl for NULL to determine
whether TLS is used for connection is a bit of a leaky abstraction, as that's
an OpenSSL specific struct member. This sets the requirement that all TLS
implementations use a pointer named SSL, and that the pointer is set to N

Personally I'm more interested in a library like Amazon's which is
trying to do less rather than more. I would rather a simpler, better
tested, easier to audit code-base than one with more features and more
complications.

No one has volunteered that I recall, so the baton is yours.
Seems like I'm not getting any traction in convincing people that
back-patching this change is wise. To get this closed out before
the CF starts, I'm just going to put it into HEAD/v13 and call it
a day.
I remain of the opinion that we'll probably regret not doing
anything in the back branches, s
Hi,
One of the issues I'm fairly regularly reminded by users/customers is
that inserting into tables sharded using FDWs are rather slow. We do
even get it reported on pgsql-bugs from time to time [1].
Some of the slowness / overhead is expected, doe to the latency between
machines in the sharded

In connection with the discussion at [1], I realized that we could unwind
the hacks we've introduced --- mostly in commit 54cd4f045 --- to avoid
depending on the behavior of %.*s format in printf. Now that we always
use our own snprintf.c code, we know that it measures field widths in
bytes not ch

Looks okay to me, except I think you want

to be

As it stands, a zero request will be treated like -1 (read all the
rest of the file) while ISTM it

There is the case archive_timeout parameter is ignored after recovery works.

When the value of archive_timeout is smaller than that of checkpoint_timeout

Hi Hackers,
For Copy From Binary files, there exists below information for each
tuple/row.
1. field count(number of columns)
2. for every field, field size(column data length)
3. field data of field size(actual column data)
Currently, all the above data required at each step is read directly from
