fin-pg-rest startup issue and enum warnings

[UcDust]

Trying to run the production gcr.io/ucdlib-pubreg/fin-pg-rest 2.2.7 image fails on start of container when running start.sh.

Running docker run postgrest/postgrest bin postgrest locally seemed to bring the service up. Also changing from production to a localhost fin-pg-rest allowed the pg-rest service to start.

Even after pg-rest starts successfully though, it appears many of the services in the cluster are throwing warnings about Unable to discover enum types, retrying in 2 sec, and the client is inaccessible.
