[Pkg-roundcube-maintainers] Bug#1016182: roundcube-pgsql: bad parsing of connection parameters to posgres database

[Bernard]

Package: roundcube-pgsql
Version: 1.4.13+dfsg.1-1~deb11u1
Severity: normal

Dear Maintainer,

Context :
Two instances of poestgresql, one is listening on socket 5432 (/var/run/postgresql/.s.PGSQL.5432),
one is listening on socket 5433

roundcube database is on the 5433 instance

connection string is defined in /etc/roundcube/debian-db.php 

with
  $dbserver=urlencode('/var/run/postgresql');
  # or else $dbserver='%2Fvar%2Frun%2Fpostgresql';
  $dbport='5433';
connection is ok

with
  $dbserver='unix(/var/run/postgresql:5433)';
  $dbport='';
connection is ok

but with
  $dbserver='unix(/var/run/postgresql)';
  $dbport='5433';
log analysis shows that roundcube tries to connect thru socket 5432 to the database ":5433/roundcube"
which is not what I expected...
