Here is patch - it is not nice at this moment and it is little bit longer than I expected - but it works It supports David's syntax postgres=# select 'Hello', 'World' \gset a,b postgres=# \echo :'a' :'b' 'Hello' 'World' postgres=# select 'Hello', 'World'; ?column? │ ?column? ──────────┼────────── Hello │ World (1 row) postgres=# \gset a to few target variables postgres=# \gset a, postgres=# \echo :'a' 'Hello' Regards Pavel > > regards, tom lane
