PostgreSQL version: 9.6.1
Operating system: Ubuntu 14.04 LTS
Description:
We are using postgresql(9.6.1) for more than three months and every
two/three days once we need to restart our servers with an error "Sorry, too
many connections already". Using a script we found that the postgresql
driver query listed below is not getting closed and remain unclosed.

0 and a.attrelid = c.oid) inner join pg_catalog.pg_type t on t.oid =
a.atttypid) left outer join pg_attrdef d on a.atthasdef and d.adrelid =
a.attrelid and d.adnum = a.attnum order by n.nspname, c.relname, attnum
this query was executed three days before and remains unclosed.
We are using unixODBC driver and enabled connection pooling for 5mins. I'm
not sure whether this causing any problem.
Please help us out.
