citext on exclude using gist

[Jean Carlo Giambastiani Lopes <jean.lopes@xxxxxxxxxxxxxx>]

Hi,

I'm trying to use a citext column in the following manner without success:

create extension btree_gist;

create extension citext;

create table my_table(

    foo citext,

    bar numrange,

    primary key (foo, bar),

    exclude using gist (foo with =, bar with &&)

);

is this possible? If so, what's wrong on this snippet?

Regards,

Jean Lopes
