Hi,
What could be the cause for error message, FATAL: invalid frontend
message type 21?
My application notices that the postgres connection is gone and it
reconnects, but i'm wondering what could cause this?
I've connected with odbc (unixodbc), unixsockect and using localhost, i
always see this message.
Running postgresql in debian 8, version:
ii libpq5:amd64 9.4.13-0+deb8u1 amd64
PostgreSQL C client library
ii postgresql-9.4 9.4.13-0+deb8u1 amd64
object-relational SQL database, version 9.4 server
ii postgresql-client-9.4 9.4.13-0+deb8u1
amd64 front-end programs for PostgreSQL 9.4
