Error of insert Foreign table with postgres_fdw
Hi all,
I got error when insert a parent table by inserting a foreign table.
Environment is following:
PG 9.6.3
CentOS6
step 1.
database1: create one parent table: phone_pool, 100 inherits table: ph_xx.
phone_pool
ph_0
...
ph_99
(create trigger "phone_pool_insert_trigger" for phone_pool and insert into
phone_pool works well. The child table got the row.)
step 2:
database2:
create foreign table phone_pool_foreign for phone_pool in database1.
when insert into phone_pool_foreign. I got error like following.
"""
insert into
phone_pool_foreign(id,patrition,phone,carrier,createtime,updatetime,deleteflg)
SELECT
'35A88C4B06B3', '90', '133333330', '1', to_date('2017-08-07
11:57:33.398','yyyy-mm-dd hh24:mi:ss'), to_date('2017-08-07

You didn't show us either the whole trigger or the failing statement in
it, but I bet you forgot to schema-qualify the child table names.
postgres_fdw runs the remote session with a very restrictive search_path,
just pg_catalog if memory serves. It's generally bad practice for
triggers to rely on the prevailing search path in any case.

Thanks Tom. Add the schema "public" in trigger solve my question.
