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.

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?
