 -- to_char
 SET lc_time TO 'tr_TR';
+ERROR:  invalid value for parameter "lc_time": "tr_TR"
 SELECT to_char(date '2010-02-01', 'DD TMMON YYYY');

Looks like you may not have Turkish locale installed?  Try

locale -a | grep tr_TR

If you don't see "tr_TR.utf8" or some variant spelling of that,
the collate.linux.utf8 test is not gonna pass.  The required
package is probably some sub-package of glibc.

A workaround if you don't want to install more stuff is to run the
regression tests in C locale, so that that test script gets skipped.
