I have compiled postgres 1.8.5 on Windows XP from source using MinGW, however the GIST index cannot be created since the following errors pop up:
HINT: You must specify an operator class for the index or define a default operator class for the data type. ERROR: data type character varying has no default operator class for access method "gist"
> HINT: You must specify an operator class for the index or define a
> default operator class for the data type.
> ERROR: data type character varying has no default operator class for
> access method "gist"
use contrib/btree_gist module: compile it and add to your database by command
'psql DB < btree_gist.sql'.
