Bug reference: 17294
Logged by: Ilya Anfimov
Email address: ilan(at)tzirechnoy(dot)com
PostgreSQL version: 14.1
Operating system: Devuan GNU/linux beowulf
Description:
I found that on 14.0 and 14.1 the server gives the error when I try to
create spgist index on a varchar field.
Note, that on 9.4 - 13 servers this test worked fine.
ilank=*> create table test (a text, b varchar);
CREATE TABLE
ilank=*> create index on test using spgist (a);
CREATE INDEX
ilank=*> create index on test using spgist (b);
ERROR: compress method must be defined when leaf type is different from
input type
