Hi,
I tested psql and pg_dump after application of this patch, from the
following perspectives:
- "\dRp+" and "\d <table-name>" (added by the patch, for PostgreSQL
15) show row filters associated with publications and specified
tables, respectively.
- psql is able to connect to the same or older server version
- pg_dump is able to dump from the same or older server version
- dumps can be loaded into newer server versions than that of pg_dump
- PostgreSQL v9 doesn't support publications
- Only PostgreSQL v15 supports row filters (via the patch)
So specifically I tested the following versions (built from the stable
branch): 9.2, 9.6, 10, 11, 12, 13, 14 and 15 and used the following
publication definitions:
create table test1(i int primary key);
create table test2(i int primary key, j text);
create schema myschema;
create table myschema.test3(i int primary key, j text, k text);
create publication pub1 for all tables;
create publication pub2 for table test1 [ where (i > 100); ]
create publication pub3 for table test1 [ where (i > 50), test2 where
(i > 100), myschema.test3 where (i > 200) ] with (publish = 'insert,
update');
(note that for v9, only the above tables and schemas can be defined,
as publications are not supported, and only the row filter "where"
clauses can be defined on v15)
I tested:
- v15 psql connecting to same and older versions, and using "\dRp+"
and "\d <table-name>" commands
- v15 pg_dump, dumping the above definitions from the same or older
server versions
- Loading dumps from older or same (v15) server version into a v15 server.
I did not detect any issues.
