metadata development

Happy spring.

I am new to postgres/postgis and am trying to figure out the best way to approach documenting metadata within postgres.  Has there been anything developed to add FGDC or Dublin Core standard metadata records into postgres for each table within the database?  Is there any program that can access postgres to insert metadata based on a standard or any other way to document metadata for a postgres database?  Any help, suggestions or advice from prior experiences would be greatly appreciated.

Thanks in advance.
