Database Maintenance

Regardless of whether you choose to run GoToSocial with SQLite or Postgres, you may need to occasionally take maintenance steps to keep your database running well.


Though the maintenance tips provided here are intended to be non-destructive, you should backup your database before manually performing maintenance. That way if you mistype something or accidentally run a bad command, you can restore your backup and try again.


Manually creating, deleting, or updating entries in your GoToSocial database is heavily discouraged, and such commands are not provided here. Even if you think you know what you are doing, running DELETE statements etc. may introduce issues that are very difficult to debug. The maintenance tips below are designed to help with the smooth running of your instance; they will not save your ass if you have manually gone into your database and hacked at entries, tables, and indexes.


To do manual SQLite maintenance, you should first install the SQLite command line tool sqlite3 on the same machine that your GoToSocial sqlite.db file is stored on. See here for details about sqlite3.

Analyze / Optimize

Following SQLite best practice, GoToSocial runs the optimize SQLite pragma with analysis_limit=1000 on closing database connections to keep index information up to date.

After each set of database migrations (eg., when starting a newer version of GoToSocial), GoToSocial will run ANALYZE to ensure that any indexes added or removed by migrations are taken into account correctly by the query planner.

The ANALYZE command may take ~10 minutes depending on your hardware and the size of your database file.

Because of the above automated steps, in normal circumstances you should not need to run manual ANALYZE commands against your SQLite database file.

However, if you interrupted a previous ANALYZE command, and you notice that queries are running remarkably slowly, it could be the case that the index metadata stored in SQLite's internal tables has been removed or undesirably altered.

If this is the case, you can try manually running a full ANALYZE command, by doing the following:

  1. Stop GoToSocial.
  2. While connected to your GoToSocial database file in the sqlite3 shell, run PRAGMA analysis_limit=0; ANALYZE; (this may take quite a few minutes).
  3. Start GoToSocial.

See here for more info.


GoToSocial does not currently enable auto-vacuum for SQLite. To repack the database file to an optimal size you may want to run a VACUUM command on your SQLite database periodically (eg., every few months).

You can see lots of information about the VACUUM command here.

The basic steps are:

  1. Stop GoToSocial.
  2. While connected to your GoToSocial database file in the sqlite3 shell, run VACUUM; (this may take quite a few minutes).
  3. Start GoToSocial.
