When creating tables in Postgres, inline PRIMARY keys are now escaped properly

For reference, before this PR, I got this error message:

db_1            | ERROR:  column "userid" named in key does not exist at character 168
db_1            | STATEMENT:  CREATE TABLE "Sid_Pomelo_Models_Users" (
db_1            |               "userID" BIGINT NOT NULL,
db_1            |               "emailAddress" CHARACTER VARYING(255) NOT NULL,
db_1            |               "password" CHARACTER VARYING(100) NOT NULL,
db_1            |               PRIMARY KEY (userID)
db_1            |       )
