For the PR i checked that liquibase recognized the (0)::real as 0 in postgresql, using the sql provided in the issue:

CREATE TABLE community (
  id text NOT NULL DEFAULT,
  "name" text NULL,
  "number" text NULL,
  division text NULL,
  latitude real DEFAULT (0)::real,
  longitude real DEFAULT (0)::real,
  latilong point NULL DEFAULT '(0,0)'::point,
  created_at timestamptz NULL DEFAULT now(),
  updated_at timestamptz NULL
);

The error does not happend anymore with this sql and i got this output with liquibase snapshot --log-level=info:

    Liquibase command 'snapshot' was executed successfully.

Liquibase recognizes (0)::real as 0 (as you can see in longitude and latitude defaultavalue).
