AFAIK to remove an existing filter use ALTER PUBLICATION ... SET TABLE
but do not specify any filter.
For example,
test_pub=# create table t1(a int primary key);
CREATE TABLE
test_pub=# create publication p1 for table t1 where (a > 1);
CREATE PUBLICATION
test_pub=# create publication p2 for table t1 where (a > 2);
CREATE PUBLICATION
test_pub=# \d+ t1
Table "public.t1"
Column | Type | Collation | Nullable | Default | Storage |
Compression | Stats target | Description
--------+---------+-----------+----------+---------+---------+-------------+--------------+-------------
a | integer | | not null | | plain |
| |
Indexes:
"t1_pkey" PRIMARY KEY, btree (a)
Publications:
"p1" WHERE ((a > 1))
"p2" WHERE ((a > 2))
Access method: heap
test_pub=# alter publication p1 set table t1;
ALTER PUBLICATION
test_pub=# \d+ t1
Table "public.t1"
Column | Type | Collation | Nullable | Default | Storage |
Compression | Stats target | Description
--------+---------+-----------+----------+---------+---------+-------------+--------------+-------------
a | integer | | not null | | plain |

Indexes:
"t1_pkey" PRIMARY KEY, btree (a)

"p2" WHERE ((a > 2))
