How to Dump the Data From One PostgreSQL Table
Below is the command to use when you would like to dump only the data from a postgreSQL table. There are other options to use to dump the schema, multiple tables, exclude certain tables, or backup the entire database but these command line switches will dump only the data from one postgreSQL table.
In the below example replace table_name with the name of the table you are backing up, file_name with the name of the output file (optionally add a path to the file name), and database_name with the name of the database where the table is located.
