Hi all,

I have some very experimental code to enable dynamic memory allocation
of shared memory for postgresql backend processes. The source code in
the repository is not complete yet. Moreover it is not immediately
useful by itself. However it might serve as the basis to implement
higher-level features. Such as expanding hash-tables or other data
structures to share data between backends. Ultimately it might be used
for an in-memory data store usable via FDW interface. Despite such
higher level features are not available yet the code anyway might be
interesting for curious eyes.


The first stage of this project was funded by Postgres Pro. Many
thanks to this wonderful team.
