Hi Euler,

FYI - the last-known-good "main" patch has been broken in the cfbot
for the last couple of days due to a recent commit [1] on the HEAD.

To keep the cfbot happy I have re-based it.

In this same post (so that they will not be misplaced and so they
remain working with HEAD) I am also re-attaching all of my currently
pending "incremental" patches. These are either awaiting merge back
into the "main" patch and/or they are awaiting review.

~

PSA 5 patches:

v29-0001 = the latest "main" patch (was
v28-0001-Row-filter-for-logical-replication.patch from [2]) is now
rebased to HEAD.

v29-0002 = my tab auto-complete patch (was
v1-0001-Add-tab-auto-complete-support-for-the-Row-Filter-.patch from
[3]) awaiting merge.

v29-0003 = my cache updates patch (was
v26-0002-ExprState-cache-modifications.patch from [4]) awaiting merge.

v29-0004 = my filter validation replica identity patch (was
v28-0002-Row-filter-validation-replica-identity.patch from [5])
awaiting review/merge.

v29-0005 = my filter validation walker POC patch (was
v28-0003-POC-row-filter-walker-validation.patch from [6]) awaiting
feedback.

~

It is getting increasingly time-consuming to maintain and track all
these separate patches. If possible, please merge them back into the
"main" patch.
