shp2pgsql -S option seems to fail, and is missing in doc

[nicklas]

Hallo

here is a problem to load points from a shapefile with type multipoint  http://gis.stackexchange.com/questions/5213/problem-loading-os-opendata-multipoint-shapefile-into-postgis

I checked the data the user is providing and if loaded with SPIT I find that all geometries gets true for ST_Issimple and none has more than one point.

In spite of that using the -S option still gives Multipoint

First, shouldn't -S option in this case create POINT of all geometries?

Second, what if it would have been one MULTIPOINT geometry in the shape, what to do? I thought there where some option to force all geometries to multi instead. I think SPIT does (and also not sets any constraint)

And -S option seems to be missing in documentation, and in the help in shap2pgsql -w option seems to be missing instead.

I have only tried in trunk version, but I have assumed it is the same in 1.5

According to Paul, -w is an "old" option that is going away (or he'd like it to go away) so it is for now becoming undocumented. That's why it is missing in some docs.

-S should be documented though, and should (will shortly) work for multipoints.

-1. I'd like to keep the -w option, as it's very useful for quickly dumping WKT out from shapefiles - it's helped me out enormously in the field on several occasions. I'd say document it, but switch it to 1.0+ format.

I'd like to keep -w too (is that a -1 we are doing a not vote right :) )

In some cases where you have badly mangled geometries, its much easier to fix the output if it's in WKT format or as Mark says, more closely inspect it.

Okay your persuasive arguments have changed his mind. I'll put it back into the docs ;-).

Resolved in trunk in revision 6922. -S now creates POINTS from MULTIPOINT shapefiles.

If you have one POINT in a MULTIPOINT shapefile, that's the bug described in #864.
