Indentation make the table hard to read. Could you please use something like: 
CREATE TABLE RudderSysEvents (
    id                     bigint         PRIMARY KEY default nextval('serial')
  , executionDate timestamp with time zone NOT NULL
  , nodeId             text            NOT NULL CHECK (nodeId <> '')
...
)
?
Or anything better, that's just the first formating I though of. 
For reference, Postgres docs use that: http://www.postgresql.org/docs/9.1/static/sql-createtable.html#SQL-CREATETABLE-EXAMPLES
