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}}
