Customer reports failed installation when using an external PostGres instance.  The log message reads  as seen below:

-------------------------------------------------------------------------------------------------

3) [Guice/ErrorInjectingConstructor]: SchemaInitializationException: 
Migration 1__optimize_user_search.sql failed
--------------------------------------------
SQL State  : 58P01
Error Code : 0
Message    : ERROR: could not open extension control file "/usr/pgsql-13/share/extension/pg_trgm.control": No such file or directory
Location   : che-schema/5.11.0/postgresql/1__optimize_user_search.sql (/file:/home/user/codeready/tomcat/webapps/api/WEB-INF/lib/che-core-sql-schema-7.40.3-SNAPSHOT.jar!/che-schema/5.11.0/postgresql/1__optimize_user_search.sql)
Line       : 15
Statement  : CREATE EXTENSION IF NOT EXISTS pg_trgm

Note the customer is using PostGres 13.2, not the 13.3 described in the Installation Guide.

Could we please validate the external db installation still works as described in the docs?
