You can give it for multiple tables. See below as an example:

> postgres=> CREATE TABLE data1(c1 INT PRIMARY KEY, c2 VARCHAR(10));
> CREATE TABLE
> postgres=> CREATE TABLE data2(c1 INT PRIMARY KEY, c2 VARCHAR(10));
> CREATE TABLE

> CREATE PUBLICATION

postgres=# CREATE PUBLICATION pub_data_1 FOR TABLE data1 WHERE (c1 >
10), data2 WHERE (c1 < 1000);
CREATE PUBLICATION
