[postgis-users] Problems using ST_Contains to check if a linestring is included in a multilinestring

[Jochen Woidich]

Hello,

I'm pretty new to postgis and mailing lists, so please excuse if I'm
breaking any conventions. :)

I'm trying to use ST_Contains to check if a certain linestring is
included in a multilinestring. This seems to work fine until the
linestring grows.

This query (http://paste.frubar.net/13291) should imho return true for
both calls, but only the first one equals to true.

Any hint on what i'm doing wrong?

PostgreSQL 9.0, PostGIS v1.5.2-3, running on Windows.
