support append and update

[eczajk1]

It didn't look like -update and -append were supported. Hope this is useful.

FYI, my use case is loading a PostgreSQL table from a File Geodatabase (ESRI/OpenFileGDB). This is the ogr2ogr statement I am trying to emulate:

ogr2ogr -f PostgreSQL -skipfailures -append -update PG:"host=localhost user=postgres dbname=mydb password=abc123" -nln myschema.mylayer mygeodatabase.gdb targetlayer

I am actually having trouble getting the result I want. Like, on this line, if I do:

console.log('ogr2ogr', args.join(' '))

... it prints the exact statement I need. But when it spawns the process, it is "Unable to open the datasource ... with the following drivers..."

If I copy/paste it, it works fine. I'm on Windows, which I'm pretty sure is contributing to my problem.

btw, I think my issue is related to this issue, but is basically irrelevant to the PR
