row description is equal to -1, which is not correct.
Does someone know where this modifier is calculated? Is this a bug or
intention behavior?

Hello, colleagues,
I have one question related to my current measurements results.
I am fetching integers in text format like:
Select * from table limit 1000. It take 18.5 seconds to finish and the
transfer data is 633 MB.
When I fetching the same data using binary cursor, the transfer data
Dear hackers,
I know that it is possible to receive packets in binary format using
declare binary cursor and than fetching the result.
But is it possible just using ordinary select from simple query to specify
that I want to receive the result in binary?
Best regards,

But I strongly doubt that a code path that netsout to more kernel calls
will win.*

Dear community,
I am really curious what was the original intention of using the
PqSendBuffer and is it possible to remove it now.
Currently all messages are copied from StringInfo to this buffer and sent,
which from my point of view is redundant operation.
It is possible to directly send message
