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“
