I'm not sure if this is the best subject line, and I apologize in advanced for the cross-posting, but I've been trying to get past a piece of code for two days now, and seem to have narrowed where a show stopping crash is occurring...
I keep getting:
psql:../sql/schedpak.sql:257: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:../sql/schedpak.sql:257: connection to server was lost
Process SQL exited abnormally with code 2
when I return from a plr function:
select * from pareto_set_as_gpx( 1, 20678 );
I'm a little handicapped as I'm not used to debugging by trial and
error, and just don't know what else I can do. I've attached a crash
report, and don't know if this is a problem with the PL/R module, the
libR.dylib module, or something I'm doing incorrectly. I've been using
this code for months now, and added another column to the type
definition, which seemed to break something.
Does the following indicate that libR.dylib is causing this crash?
