I recently needed to copy a single table in a database from server A to server B. This required dumping the table on server A and restoring the table on server B.
To dump a single table in postgres, use the
pg_dump --table <TABLE_NAME> -FC <DATABASE_NAME> > <TABLE_NAME>.sql
If you are on UBUNTU, and are using defaults across the board, this will probably require you to switch user to postgres first.
sudo su - postgres
After you have copied
<TABLE_NAME>.sql to the new machine, you can restore that same table using the following comamnd:
pg_restore --dbname <DATABASE_NAME --table=<TABLE_NAME> <TABLE_NAME>.sql
