    85     * Database fixes:

    86 	- Due to an error in usertransport's argument parsing, it is

    87 	  possible that some users' transport-ID points to the erroneous

    88 	  transport 'domain'. To fix that error in your database, execute

    89 	  the following SQL statement:

    90 

    91 	   UPDATE users SET tid = NULL

    92    	    WHERE tid = (SELECT tid FROM transport WHERE transport = 'domain');

    93 

    94 	- If you are using Dovecot < v1.2.0:

    95 	  You have to replace the database FUNCTION dovecotpassword().

    96 	  (see file: pgsql/create_tables.pgsql)

    97 	  The service_set.ssid was selected unconditionally. This may cause

    98 	  an empty result, which will make logins impossible.
