PostgreSQL docker images with pg_bigm installed.
bitnami/postgresql and postgres are supported.
As in the pg_bugm installation guide,
your postgresql.conf file should contains shared_preload_libraries = pg_bigm. However, I personally have found no issues for not doing this.
For bitnami docker images, you can set this by POSTGRESQL_SHARED_PRELOAD_LIBRARIES env variable.
Please refer to Preloading shared libraries section in https://hub.docker.com/r/bitnami/postgresql
For bitnami helm charts, you can set this by postgresqlSharedPreloadLibraries in your value.yaml.
Please refer to https://github.com/bitnami/charts/tree/main/bitnami/postgresql#postgresql-common-parameters
For official postgres images, you need to customize whole postgresql.conf file.
Please refer to Database Configuration section in https://hub.docker.com/_/postgres
