pg_dumpall

Extract a PostgreSQL database cluster into a script file or other archive file. More information: https://www.postgresql.org/docs/current/app-pg-dumpall.html.

• Dump all databases:

pg_dumpall > {{path/to/file.sql}}

• Dump all databases using a specific username:

pg_dumpall --username={{username}} > {{path/to/file.sql}}

• Same as above, customize host and port:

pg_dumpall -h {{host}} -p {{port}} > {{output_file.sql}}

• Dump all databases into a custom-format archive file with moderate compression:

pg_dumpall -Fc > {{output_file.dump}}

• Dump only database data into an SQL-script file:

pg_dumpall --data-only > {{path/to/file.sql}}

• Dump only schema (data definitions) into an SQL-script file:

pg_dumpall -s > {{output_file.sql}}
