Hi!
Thanks for all of your interest!
My test PC is Win7 (64-bit), and equipped with 8GB of memory.
In this java project, I configured VM option as:

Hi,
I'm looking for a data type to store numerically labelled hierarchical data,
such as section.subsection.paragraph numbers (e.g. '1.5.3', '1.10.2', '6.30').
The closest data type that I have found is ltree. However, the collation order
is inappropriate: it would put '1.10.2' before '1.5.3',

You can't just make them share the data dir (for example: what about
caches in memory?)
Probably what you want is streaming replication:

Hi all!
I have two servers, which share a large mounted drive. I would like to
share postgres databases between them dynamically so that when one makes
changes, they are immediately available in the other.
I tried moving the data directory over to the mounted drive, and pointing
both postgresql.

That is good and I will effect that change here; but as far as I can see
