So it never makes sense to specify HASHES for operators that do not represent equality . This may be the source text in the procedural language itself ( like for PL / Tcl ) , a pathname to a file or anything else that tells the call handler what to do in detail . It 's up to the call handler to fetch the pg_proc entry and to analyze the argument and return types of the called procedure . Similarly , the proposal on agriculture made by the African Group last March defines clear interests and objectives and provides a precise content to what could be a special and differential treatment in this sector . The backend must be started with the - i option to allow non-local clients to connect . In that case you 'll need to figure out which one to use and run configure again , this time giving the - - with-template = TEMPLATE option to make the right file be chosen .
