# plpgsql-ulid-generator
PostgreSQL function for generating ULID as UUID on plpgsql
```sql
select ulid('2022-01-01'); -- 017e12ef-9c00-0000-0000-000000000000
select ulid(); -- 017e61c1-d833-4af7-70c7-8444ae1d207a
```
Used for monotonic ids and for partitioning tables using them
```plpgsql
CREATE TABLE "table" (
id uuid primary key not null default ulid(),
...
) partition by range (id);
CREATE TABLE table_2021 partition of "table" for values
from
(ulid('2021-01-01'))
to
(ulid('2022-01-01'));
```
The UUID format in Postgres is more compact than text as in ULID specification
