Please enter a FULL description of your problem:
------------------------------------------------
I initialized dbcluster with --locale=cs_CZ.UTF-8 and created database
with --encoding=unicode. Following script generates error:
-- -*- coding: iso-8859-2 -*-
set client_encoding to LATIN2;
create table t (txt text);
begin;
--inserted character is latin small letter r with caron, coded in iso
8859-2; escaped as \370
insert into t values ('ř');
insert into t values ('\\@');
commit;
-- end of script
, generates
SET
CREATE TABLE
BEGIN
psql:test.sql:7: invalid command \
psql:test.sql:9: ERROR:  parser: unterminated quoted string at or near "'
commit;" at character 52
. I think this is a bug, because the script is syntactically OK and work
fine on database with server_encoding=latin2.

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:

 Above example is reproducible.




If you know how this problem might be fixed, list the solution below:

 Perhaps lc_ctype=cs_CZ.UTF-8 is used when script is read.
