I'm trying to use timestamp ranges to keep track of the values particular items had over time, but I'm unable to create a table as follows:
test=# create extension btree_gist;
CREATE EXTENSION
test=# create table v(item uuid, lifetime tstzrange, value text,
test(# exclude using gist (item with =, lifetime with &&));
ERROR: data type uuid 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.
test=#
It works fine if I make item a text field.
test=# create table v(item text, lifetime tstzrange, value text,
test(# exclude using gist (item with =, lifetime with &&));
CREATE TABLE
test=#
Is there any reason that the required uuid access method isn't implemented? How hard is it to implement this?
I would also like to see btree_gist support uuid's.
I found a related thread from two years ago: http://postgresql.1045698.n5.nabble.com/UUID-datatype-GiST-index-support-td4722960.html
