[postgis-devel] sql files proliferation

[strk]

The postgis*sql* files are becoming a major part
of the distribution (as number of files).
What about having a single sql for each postgres version ?
Or - better - use some preprocessing to keep in common
things that are common and spilt things that need to be
splitted ?

I need to move geometry_column creation out of _common_
into each of version-specific files because for PG75 there
is no need of attrelid oid, varattnum int and stats histogram2d;
this already happended for schema support changes (addGeometryColumn,
dropGeoemtryColumn, fix_geometry_columns) and is getting boring.
