What version of PostgreSQL are you running? The error seems to indicate
that you don't have the crosstab(text,text) form of the function.
In psql do:
contrib_regression=# \df crosstab
List of functions
Schema | Name | Result data type | Argument data types | Type
--------+----------+------------------+---------------------+--------
public | crosstab | SETOF record | text | normal
public | crosstab | SETOF record | text, integer | normal
public | crosstab | SETOF record | text, text | normal
(3 rows)
Does it look like this?
