[bitnami/postgresql] unable to modify shared_buffers

[shaykeren]

Name and Version

bitnami/postgresql

What architecture are you using?

None

What steps will reproduce the bug?

shared_buffers setting is not set, although I changed the values file with shared_buffers = '7000MB'
I found that this file override my settings ->
/bitnami/postgresql/data/postgresql.auto.conf 3 shared_buffers 1GB

The following command returns an output of '1GB':
SHOW shared_buffers; 1GB

The following command returns an output of
/opt/bitnami/postgresql/conf/conf.d/override.conf 1 shared_buffers 800MB
/bitnami/postgresql/data/postgresql.auto.conf 3 shared_buffers 1GB

SELECT sourcefile, sourceline, name, setting 
FROM pg_file_settings 
WHERE name = 'shared_buffers';

Are you using any custom parameters or values?

postgresql:
  primary:
    extendedConfiguration: |
      shared_buffers = '7000MB'

What is the expected behavior?

shared_buffers should be set to 7GB

What do you see instead?

shared_buffers is 1 GB
