Hard/soft upgrade need to be tested

[pramsey]

'ii) In terms of upgrading from 1.3, I've just remembered that Olivier altered the signature of the ST_AsSVG() function, plus I've altered the ST_Extent() function signature with GBT#93. So we really need to put these changes into the PostGIS soft/hard upgrade scripts. Paul, are you able to take a look at this?'

From 1.3 to 1.4 on export functions prototypes and parameters values changes:

ST_AsGML add an optional fourth 'option' parameter: text ST_AsGML(integer version, geometry g1, integer precision, integer options);

ST_AsGML and ST_AsKML precision parameter refered to decimal digits (rather than siginificant digits)

ST_AsGeoJson options values are now:

• 0: means no option (default value)
• 1: GeoJSON Bbox
• 2: GeoJSON Short CRS (e.g EPSG:4326)
• 4: GeoJSON Long CRS (e.g urn:ogc:def:crs:EPSG:4326)

Rather than:

• 0: means no option (default value)
• 1: GeoJson? CRS
• 2: GeoJson? Bbox

Hard upgrade tested and updated. Seems to work fine from 1.3 -> 1.4. Soft upgrade tested and updated. We have some dropped signatures where there are no new definitions for old functions.

I think this is an non-issue.
