If you need a server-side murmur3 function
- one alternative is the https://github.com/markokr/pghashlib extension.
psql (15.2 (Debian 15.2-2))
Type "help" for help.
db=# create extension hashlib;
CREATE EXTENSION
db=#
select hash_string('', 'murmur3');
select hash_string('a', 'murmur3');
select hash_string('abcdefg', 'murmur3');
select encode(hash128_string('abcdefg', 'murmur3'), 'hex');

In my test, I have used this fork:
https://github.com/bgdevlab/pghashlib/tree/bgdevlab/builds
RUN mkdir -p /pghashlib \
&& git clone --depth 1 --branch bgdevlab/builds
https://github.com/bgdevlab/pghashlib.git /pghashlib \
&& cd /pghashlib \
&& make USE_PGXS=1 \
&& make USE_PGXS=1 install \
&& rm -rf /pghashlib

Imre
