Thanks for the updated patch.
Some review comments:

doc/src/sgml/ref/create_publication.sgml
(1) improve comment
+ /* Set up a pstate to parse with */

"pstate" is the variable name, better to use "ParseState".

src/test/subscription/t/025_row_filter.pl
(2) rename TAP test 025 to 026
I suggest that the t/025_row_filter.pl TAP test should be renamed to
026 now because 025 is being used by some schema TAP test.

(3) whitespace errors
The 0006 patch applies with several whitespace errors.

(4) fix crash
The pgoutput.c patch that I previously posted on this thread needs to
be applied to fix the coredump issue reported by Tang-san.
While that fixes the crash, I haven't tracked through to see
where/whether the expression nodes are actually freed or whether now
there is a possible memory leak issue that may need further
investigation.
