Yes, actually I tried it yesterday but just to be sure I tried it again
today - no errors:

....
NOTICE: i = 9999800
NOTICE: i = 9999900
NOTICE: i = 10000000

Total query runtime: 2231947 ms.
1 row retrieved.

The "letters" variable used in the test (in case you have the time to
try it yourself):
letters varchar(255) := 'юяьъщшчцфjklmnopqrstuvwxyz';

And the database definition:

CREATE DATABASE spb
WITH OWNER = postgres
ENCODING = 'UTF8'
LC_COLLATE = 'Bulgarian_Bulgaria.1251'
LC_CTYPE = 'Bulgarian_Bulgaria.1251'
CONNECTION LIMIT = -1;

The system locale is "Bulgarian (Bulgaria)".
