[postmodern-devel] bug in query (or deeper)

[Marijn Haverbeke]

Ryszard,

Thanks for the report. That is rather clumsy indeed -- what happens is
that the libary sends the start of a message to the server, and then
raises an error when it tries to send the list as a string. After such
an error, it will try to re-synchronize the connection, so that it can
be used again without reconnecting, but a half-sent message puts the
connection in such a broken state that it can not be re-synchronized
-- hence the hanging you saw, the server wasn't responding anymore.

I pushed a simple patch that uses check-type to make sure queries (and
query names) passed to the cl-postgres functions are string values.

Cheers,
Marijn
