[pgpool-general: 5687] connecting to pgpool (3.6.4) via python pg8000 module

[Shay Cohavi]

Hi,

postgres9.3.5
pgpool 3.6.4

I having problem connecting to postgresql servers via pgpool using python
pg8000 module (which worked before on an older pgpool versions - 3.4.3):

# PGPASSWORD=postgres psql -h *10.65.150.86* -p *9999* -U postgres -c "show
pool_nodes"

 node_id |   hostname    | port | status | lb_weight |  role   | select_cnt
| load_balance_node | replication_delay
---------+---------------+------+--------+-----------+---------+------------+-------------------+-------------------
 0 | 10.65.150.200 | 5432 | up     | 0.500000  | standby | 712678     |
false             | 0
 1 | 10.65.150.201 | 5432 | up     | 0.500000  | primary | 51705100   |
true              | 0
(2 rows)


*connecting via cli to pgpool port is working as expected:*

# *PGPASSWORD=postgres psql -U postgres -h 10.65.150.86 -p 9999 -d postgres*
psql (9.3.5)
Type "help" for help.

postgres=#

port=5432, database='manager')*

Please advice, since this issue didnt came up with the older pgpool (3.4.3)
