[postgis-users] [Longest distance between two from list of points?]

[Sergiusz Pawlowicz]

I have about ten thousands of points stored in a postgis database.

I need to find the longest distance between two of the furthest of
them from each other, something like bounding box, but let's say
"bounding line".

Any suggestions?

I browse the archives but there was no clearly opensource answer, the
only one was suggesting some FME-like commercial products.

Thanks,
Serge
