The easy way to do this on Debian/ubuntu, if you're building something that packages exist for, is (eg):

sudo apt-get build-dep postgresql

This downloads and installs all the dependencies required to compile postgresql.

And voila!  Here is the backtrace:

Thankyou VERY much for taking the time to collect this information.

It appears to be crashing while building an index:

CREATE INDEX itransf ON transactions USING btree
(loccode, startdtact, starttmact);

I don't know PostgreSQL's innards well enough to know much more than that, but others do and may well check this out.

Are you able to distribute your dataset - if not to the general public, then to someone interested in identifying the fault?

Does the same dataset crash Pg when restored on another machine?

so, do I leave this here, or do I send it to pgsql-bugs?
