HELP! ... pg_locale ???

Hello folks,

I got a headache now, cause our admin played with postgres settings,
something about pg_locale, as he says. Perhaps the reason is
elsewhere, i dont know.

As result, now all queries, written inside the php code on multiply lines,
returns the following:

ERROR: parser: parse error at or near " "

The same query, pasted to psql, works well.
The same query written on single line in php code works well.
But i see that my older scripts with multiply line queries works well.

Whats up?! Why?

There is no errors in this code:
------
$result = @pg_exec($db,"
SET DATESTYLE = 'ISO';
SELECT DISTINCT
meznieciba,
date_part('day',date(datums)) AS dd,
date_part('month',date(datums)) AS mm,
date_part('year',date(datums)) AS yyyy,
galvene,
kajene
FROM izsoles
WHERE datums = '$datums'") or die(pg_errormessage());
------
it works fine when written on the single line
but now i see the above stupid error message..

it so funny to have to rewrite queries to single line?..

Sandis
