Operating system:   Centos 7
Description:

Connected via psql
issuing a command like : SELECT * FROM generate_series (1, 1000);
meta command \p shows the query buffer
meta command \reset tells "Query buffer reset (cleared)."
but meta command \p still shows the query buffer and meta command \g execute
the query
Is this the normal behavior ?
It seems to me that the query buffer should be empty after issuing \reset
