Where Clause not being applied to all tables in a publication

От

When adding more than one table to a logical replication publication with a where clause, the where clause is only applied to a single table in the publication, not all of them. 

Basic test case:

testdb=# create table foo (id bigserial primary key);
CREATE TABLE
testdb=# create table bar  (id bigserial primary key);
CREATE TABLE
testdb=# CREATE PUBLICATION test_pub for table foo,bar WHERE (id = 1);
CREATE PUBLICATION
testdb=# select * from pg_publication_tables \gx
-[ RECORD 1 ]--------
pubname    | test_pub
schemaname | public
tablename  | foo
attnames   | {id}
rowfilter  |
-[ RECORD 2 ]--------
pubname    | test_pub
schemaname | public
tablename  | bar
attnames   | {id}
rowfilter  | (id = 1)

Thanks,
Brad

The observed behavior is precisely what the syntax describes.
