[postgis-users] GIST index create failure

[Dave Stone]

I'm trying to create a spatial index on a simple table with a geometry 
column. I've tried doing this via the PostgreSQL command line and using 
phppgAdmin. So for table 'loccoords' with column 'geom' of type 
'geometry', the SQL is:

create index loccoords_gistix on loccoords using gist(geom 
gist_geometry_ops);

and the result is:
server closed the connection unexpectedly
         This probably means the server terminated abnormally
         before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

Has anyone met this before? I have successfully created a GIST index 
before (on an earlier version of the same table, with fewer than the 
present 357 rows).

I'm running PostgreSQL 8.0.8 and PostGIS 1.0.6.

Any suggestions gratefully received!
