Hi,
Trying to create multiple database instances of PostgreSQL 9.6 In this case , trying to create 2nd instance with port 5434/5435. *1st attempt:* *Create new database cluster : * C:\Program Files\PostgreSQL\9.6\installer\server>initcluster.vbs postgres postgr es 12345 "C:\Program Files\PostgreSQL\9.6" "C:\Program Files\PostgreSQL\9.6\data 5434" 5433 DEFAULT *Register as Windows Service: * C:\Program Files\PostgreSQL\9.6\installer\server>startupcfg.vbs 9.6 postgres 123 45 "C:\Program Files\PostgreSQL\9.6" "C:\Program Files\PostgreSQL\9.6\data5434" postgresql-x64-9.6-5434 But after this step, new service is supposed to be found in services.msc which is not successful. (Reference http://stackoverflow.com/questions/6241793/are- independent-instances-of-postgresql-possible ) *2nd attempt :* *Create new database cluster : * C:\Program Files\PostgreSQL\9.6\bin>initdb C:\PostgreSQL\9.6\data5435 The files belonging to this database system will be owned by user "Administrator ". This user must also own the server process. The database cluster will be initialized with locale "English_United States.1252 ". The default database encoding has accordingly been set to "WIN1252". The default text search configuration will be set to "english". Data page checksums are disabled. creating directory C:/PostgreSQL/9.6/data5435 ... ok creating subdirectories ... ok selecting default max_connections ... 100 selecting default shared_buffers ... 128MB selecting dynamic shared memory implementation ... windows creating configuration files ... ok running bootstrap script ... ok performing post-bootstrap initialization ... ok syncing data to disk ... ok WARNING: enabling "trust" authentication for local connections You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb.
