I upgraded a Debian 9 "Stretch" server to Debian 10 "Buster", which
also
upgrades Mediawiki to version 1.31.
Trying to run update.php, it fails with "Cannot access the database: No
database connection":
/var/lib/mediawiki/maintenance# php update.php
MediaWiki 1.31.10 Updater
Your composer.lock file is up to date with current dependencies!
[6b70dd5bdc9deadcca99506a] [no req] Wikimedia\Rdbms\DBConnectionError from line 1004 of

The database is Postgresql, and I can access it fine with psql etc.
In LocalSettings.php I have
## Database settings
$wgDBtype = "postgres";
$wgDBserver = "localhost";
$wgDBname = "wikidb";
$wgDBuser = "...hidden...";
$wgDBpassword = "...hidden...";
# Postgres specific settings
$wgDBport = "5432";
$wgDBmwschema = "mediawiki";
$wgDBts2schema = "public";
Thanks for any help...
