plpgsql function-parsing

[chris]

Hi,

I am trying to create a function that gets passed a statement as a 
string and then I need to change the table_name within the string by 
adding a "_cdc" to it, then execute the statement

ex:

string passed could be GRANT all ON authors TO bob.

then

EXECUTE GRANT all ON authors_cdc TO bob


I'm looking into parsing the string but i can't find a way to parse in a 
way that'll work. Any ideas?


Thanks,

Chris
