 -   `galloc`, which always creates globally allocated range sequences.
 -   `snowflakeid`, which creates global sequences for BIGINT sequences that
      consist of time, nodeid, and counter components. You can't use it with
      INTEGER sequences (so you can use it for `bigserial` but not for `serial`).
 -   `timeshard`, which is the older version of SnowflakeId sequence and is provided for

      (i.e., `serial`) and `int2` sequences.
