Make create postgis and postgis_topology unpackaged script automated

[robe]

Right now to generate the postgis--unpackaged.sql.in postgis-topology--unpackaged.sql.in

I just run a the "make_unpackaged.sql" query against a newly installed database with postgis / postgis_topology extensions. This I'd like to automate either by sourcing the sql files or as a autocommit job on Jenkins that will auto post whenever a change to the repo is made.

Milestone renamed

How about providing this as an SQL function instead ?

  postgis_extension_unpackage();

Note I've made generation of that script automated in the branch for the postgis_raster extension split, basing it on the drops found in uninstall + drop_before + drop_after.

See #3888 for the PR containing the automated creation of the unpackage script. It is a generic perl script that can be passed via stdin all the uninstall/drop files.

I belive this is fixed since [e7e778690c6920e3ba7b74ced6f314f6a9a5479d/git] with the presence of create_extension_unpackage.pl
