Incorrect parsing of default sysdatetime() function

[shubham-yb]

Hi Team,
If we have a date time type column with a default value ex:

ALTER TABLE [dbo].[AAFILE] ADD  CONSTRAINT [DF_AAFILE_created_on]  DEFAULT (sysdatetime()) FOR [created_on]

The function sysdatetime() gets parsed as is which is not supported by PG ex:

ALTER TABLE "public"."aafile" ALTER COLUMN "created_on" SET DEFAULT sysdatetime();

If we could convert it to now(), the PG equivalent, the error can be avoided.

Thank You for your help.
