operator does not exist: unknown => text

Hi for all. When I run:

$ ./setup.php --osm-file poland.osm.bz2 --all

script is running until:

...

END OF LOGS

From setup.php I can see that it is breaking down somewhere in --load-data function. Earlier tasks run just fine.

I also found in nominatim/sql/functions.sql, in line 982:

NEW.name := 'ref'=>NEW.postcode;

My software (system is gentoo):

mapnik-2.1.0

postgis-2.0.2-r2

osm2pgsql version from svn sources (tried with and without --64bit-ids support compiled in, same result)

postgres-9.2

geos-3.3.3

libxml2-2.9.0-r2

pear-1.9.4

PEAR-DB-1.7.14

PEAR-MDB2_Driver_pgsql-1.5.0_beta3

php-5.4.8

What is wrong?

In nominatim sources I have made a change:

1. Using sed: www-data -> osmuser but this shouldn't break anything.

Also in postgres, in pg_operator table I can't find '=>' operator but I didn't modify anything there. Any help?
