[pgpool-general: 3910] pgpool2 "invalid byte sequence for encoding "UTF8": 0xe5 0x02"

[Yura Ivanovskiy]

Hi all!
I have trouble with pgpool.
For now I use it in testing mode, at first sight all works fine. But some
query ("inserts"), finishing with error

Aug  4 18:18:43 pg1 pgpool: 2015-08-04 18:18:43: pid 18878: LOG:  Parse:
Error or notice message from backend: : DB node id: 0 backend pid: 18915
statement:
"INSERT INTO "clic" ("a_id", "app_id", "c_image_id", "c_url_id",
"count_id", "created_at", "dev_id", "ip", "type", "ua", "updated_at",
"ur_only", "w_sk", "x_fd") VALUES ('a1a99f3e-f0b5-44b1-98bb-2c10a9bd2112',
4313, 403, 174, 24, '2015-08-04 18:18:43.766423', 711675, '119.161.65.6',
1, 'Dalvik/1.6.0 H�#002" message: "invalid byte sequence for encoding
"UTF8": 0xe5 0x02"

What I doing wrong?

If I connect application without pgpool - all works without any errors.

Thanx in advance for any help!
