timescaledb-postgis:16 for ARM64 not working

[everesio]

Docker manifest inspect provides an image availability for ARM64 arch.
However when run on "amzn2.aarch64" / m6g, the initdb returns exec format error, so it is probably built for AMD not ARM.

initdb Error: error while creating the PostgreSQL instance: fork/exec /usr/lib/postgresql/16/bin/initdb: exec format error

@everesio Thanks for pointing this out.

Do you want to file a PR for this ?

[imusmanmalik]

this is not possible for now since the postgis images aren't available for arm64 here

postgis/docker-postgis#216 (comment)

Guess that we need to wait a little longer for arm64 support
