BUG #17020: meta command psql _eset does not clear the query buffer

The following bug has been logged on the website: Bug reference: 17020 Logged by: François Grandvarlet Email address: francois.grandvarlet@wanadoo.fr PostgreSQL version: 13.3 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

Yes. \p is documented as Print the current query buffer to the standard output. If the current query buffer is empty, the most recently executed query is printed instead. and \g likewise says "If the current query buffer is empty, the most recently sent query is re-executed instead". > It seems to me that the query buffer should be empty after issuing \reset It is. If you now type something, that something is a new command that's not concatenated with what you typed before. regards, tom lane
Thank you very much for your answer and your explanations. I should have read the doc more carefully.
