[postgis-users] Moving to SpatiaLite: best practice

[Paragon Corporation]

Oops slight correction.  Forget my comment about pgsql2shp.  I just realized
what I was thinking doesn't work, so you may have to dump the geometry
tables to shp and then load into SpatiaLite with the numerous loaders out
there.
 
I suppose you can chain them like pgsql2shp | shp2pgsql -w but haven't tried
that.
It would be nice if OGR2OGR supports this.  I assume that is in the works,
but I think it only supports SQLite not SpatiaLite yet.

Jose,
>From our experience -- the SQLite SQL syntax compatibility with PostgreSQL
is pretty good, so that your dump idea should more or less work with minor
massaging to load into SQLite.  Well it will probably work just fine for the
regular data if you use the -D insert format of PostgreSQL of pg_dump
http://www.postgresonline.com/downloads/special_feature/postgresql83_pg_dump
restore_cheatsheet.pdf
 
So the only issue is the geometry output.  These will probably not be
compatible.  You could use pgsql2shp and output using the -w switch which
will output to WKT.

That may just work.  Haven't tried it myself so good luck and let us know
how it turns out.

Hi,
I'm doing some very simple PostGIS-related work: I store data in a table,
and from time to time, I do simple stuff with the stored data, sometimes
even actually using the geometry column!!! Anyway, PostGIS has been very
useful so far, but I now have to move away from my work computer, and I
would like to keep on working with my laptop. One way would be to install
PostGIS on my laptop, but I am also thinking of giving my program to other
people, who might not necessarily need or want to install PostGIS. To this
end, spatialite is very handy. It's just a file, and I can use the same
PostGIS stuff I've been using up to now. However, I need to move my tables
to SpatialLite. In essence, I do have a number of tables, most of which
relate a field to a geographical table. It should be trivial to dump schema
and SQL and run it pass sqlite/spatialite. I was just wondering whether
anyone had any recommendations or ideas on "best practice".

Thanks!
Jose
