I met another problem when filtering out with the operator '~'.
Data can't be replicated as expected.

For example:
-- publisher
create table t (a text primary key);
create publication pub for table t where (a ~ 'aaa');

-- subscriber
create table t (a text primary key);
create subscription sub connection 'port=5432' publication pub;

-- publisher
insert into t values ('aaaaab');
insert into t values ('aaaaabc');
postgres=# select * from t where (a ~ 'aaa');
    a
---------
 aaaaab
 aaaaabc
(2 rows)

-- subscriber
postgres=# select * from t;
   a
--------
 aaaaab
(1 row)

The second record can’t be replicated.

By the way, when only applied 0001 patch, I couldn't reproduce this bug.
So, I think it was related to the later patches.
