Database configuration
Updating the default configuration for your Postgres database.
Postgres provides a set of sensible defaults for you database size. In some cases, these defaults can be updated. We do not recommend changing these defaults unless you know what you're doing.
Timeouts
See the Timeouts section.
Statement optimization
All Supabase projects come with the pg_stat_statements
extension installed, which tracks planning and execution statistics for all statements executed against it. These statistics can be used in order to diagnose the performance of your project.
This data can further be used in conjunction with the explain
functionality of Postgres to optimize your usage.
Managing timezones
Every Supabase database is set to UTC timezone by default. We strongly recommend keeping it this way, even if your users are in a different location. This is because it makes it much easier to calculate differences between timezones if you adopt the mental model that "everything in my database is in UTC time."
Change timezone
_10alter database postgres_10set timezone to 'America/New_York';
Full list of timezones
Get a full list of timezones supported by your database. This will return the following columns:
name
: Time zone nameabbrev
: Time zone abbreviationutc_offset
: Offset from UTC (positive means east of Greenwich)is_dst
: True if currently observing daylight savings
_10select name, abbrev, utc_offset, is_dst_10from pg_timezone_names()_10order by name;
Search for a specific timezone
Use ilike
(case insensitive search) to find specific timezones.
_10select *_10from pg_timezone_names()_10where name ilike '%york%';
