Hello Pavel,
[...] it is little bit worse. I cannot to distinguish between
SELECT\gdesc and TRUNCATE xxx\gdesc . All are valid commands and produce
empty result, so result of \gdesc command should be empty result too.
postgres=# truncate table xx\gdesc
┌──────┬──────┐
│ Name │ Type │
╞══════╪══════╡
└──────┴──────┘
(0 rows)
Hmmm. At least it is better than the previous error.
What about detecting the empty result (eg PQntuples()==0?) and writing
"Empty result" instead of the strange looking empty table above? That
would just mean skipping the PrintQueryResult call in this case?
