Creating a database dump for specific tables and entries Postgres

If those specific tables match a particular regex, You can use the regex in -t option in pg_dump.

pg_dump -D -a -t zones_seq -t interway -t "<regex>" -f /tmp/zones_seq.sql <DBNAME>

For example to dump tables which started with "test", you can use

pg_dump -D -a -t zones_seq -t interway -t "^test*" -f /tmp/zones_seq.sql <DBNAME>

Right from the manual: "Multiple tables can be selected by writing multiple -t switches"

So you need to list all of your tables

pg_dump --column-inserts -a -t zones_seq -t interway -t table_3 ... > /tmp/zones_seq.sql  

Note that if you have several table with the same prefix (or suffix) you can also use wildcards to select them with the -t parameter:

"Also, the table parameter is interpreted as a pattern according to the same rules used by psql's \d commands"
