therequirements. If I should be communicating through a different mailing list, please let me know!

that,I would really like to discuss with one of the community members about possible parts of the code that could be in
needof such reworking. If no such parts are knows, I would like to see if I could find them myself, although it could
takea substantial amount of time, so any input is welcome!
To the extent that this is independent from GSOC, I would suggest you
email the pgsql-hackers mailing list with your specific thoughts about
what optimizations you would add to PostgreSQL for aarch64. Note that
the PostgreSQL community is unlikely to accept optimziations which are
architecture-specific unless they are very clear, have very few
drawbacks, and are able to be maintained by the community.
Optimizations which slow down other, more common, platforms are very
unlikely to be accepted. Further, PostgreSQL absolutely must produce
the correct answer on all platforms and that may preclude the ability to
use certain platform-specific optimization as that could lead to
different results on different platforms.
Thanks!
