- res = ExecuteSqlQuery(fout, query->data, PGRES_TUPLES_OK); + res = ExecuteSqlQuery(fout, + "SELECT DISTINCT attrelid FROM pg_attribute " + "WHERE attacl IS NOT NULL", + PGRES_TUPLES_OK);
I'm not sure I find it an improvement to put have to look after the query text (which can be long) for the ExecStatusType. Having it separated from the query is more readable IMHO (I know we have a mix of both already, but I kind of prefer passing in the buffer).
I considered replacing them all with the pattern where we assign the block text to a char *querystr, and in fact that's done in the patch in a couple of places where the query was an if/else constant. Is that more acceptable?
