The creation of the `pg_trgm` extension needs superuser power. So,
this patch makes the extension creation in the Hydra NixOS module when
a local database is used.
If it is not possible to create this extension (remote database for
instance with nosuperuser), the creation of the `pg_trgm` index is
skipped (this index speedup queries on builds.drvpath) and warnings
are emitted:
initialising the Hydra database schema...
WARNING: Can not create extension pg_trgm: permission denied to create extension "pg_trgm"
WARNING: HINT: Temporary provide superuser role to your Hydra Postgresql user and run the script src/sql/upgrade-57.sql
WARNING: The pg_trgm index on builds.drvpath has been skipped (slower complex queries on builds.drvpath)
This allows to keep smooth migrations: the migration process doesn't
require a manual step (but this manual step is recommended on big
remote databases).
