Hey all, looking for thoughts on a feature request:I run quite a few queries, using psql, that are intended for exceptional situations. When there are no results, which is expected, I still get the table header and basic frame showing up in the output. The option I'd like is to be able to suppress the output of the empty table (and header if there is one) or possibly substitute the empty table with user-supplied text.Thinking something that is used like \gSELECT * FROM (VALUES (1)) vals (v) WHERE v = 0 \ghideifempty[SQL] \galtifempty 'No values matching 0 in vals'The names are descriptive, not suggestions...David J.

- Have you looked at the TUPLES ONLY option?
- -t
--tuples-only Turn off printing of column names and result row count footers, etc. This is equivalent to the \t command.
