Are you sure ogr2ogr is the right tool for what you want to accomplish?

Trying to use a DDL trigger seems like a roundabout way to get what you want when the problem is ogr2ogr.
So, I would back up and ask, what are you trying to do, and what information is being lost using -append?
Also, you mentioned asking this on the GDAL list, did you try the PostGIS list?

-- I have a table that is generated through ogr2ogr.
To get ogr2ogr working the way I want, I need to use the -overwrite function. If I use the append function information is lost. Something to do with the way the switches work.
Overwrite drops the existing table and also the attached trigger .
I am attempting to have the dropped table trigger a function as it is being populated by insert commands.
DDL trigger was mentioned as a possibility on the GDAL list.
Any suggestions will be welcome.
