Unable to add exclude constraint to table












0















I'm unable to create an excludes index with this schema.



create table foo_bar(
foo_id text primary key,
bar char(3) not null,
created_at timestamptz not null default current_timestamp,
system_period tstzrange not null default tstzrange(current_timestamp, null),
exclude using gist (system_period with &&)
);

create table foo_bar_history(like foo_bar);

alter table foo_bar_history add constraint exclude using gist (system_period with &&);


The final alter table line here fails with



SQL Error [42601]: ERROR: syntax error at or near "using"


I've double checked the docs, but I really can't see what I'm doing wrong here.



PostgreSQL 9.6.9 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 7.2.0-8ubuntu3.2) 7.2.0, 64-bit

          You either have to specify the constraint name after CONSTRAINT or omit that keyword altogether so that PostgreSQL picks a name itself.
