Checkmk Werk 14556: mk_postgres: support Latin-1 server encoding

ID: 14556 Title: mk_postgres: support Latin-1 server encoding Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Previously, any Postgresgl server with encoding Latin-1 would be rejected by the agent <tt>mk_postgres.py<\tt>. This is because some of the SQL queries sent by the agent contained utf-8 only characters. With this werk, the agent supports Latin-1 encoding.
