Hi @pgsql-admin@lists.postgresql.org<mailto:pgsql-admin@lists.postgresql.org> ,
I have 2 mounts /data/feed & /data/bets
I have postgres-dev server on which I have 6 feed databases (let's say a,b,c,d,e,f) and 4 bets databases(lets say g,h,i,j)
I want to group the data directories based on the databases, and they all should be running from the same instance. Can I achieve this ?
Or if not, can you suggest me a work-around to achieve this
Regards,
Phani

Look into tablespaces

Symlinks. But tablespaces are the canonical solution.

You cannot simply re-assign tablespaces to different PostreSQL
instances. You still must export and import them. You can physically
copy a tablespace location to another location (file copy) within a PG
instance, and then change the directory assignment (symlinks) for those
tablespaces. This is often used when folks need a bigger space for
their data or a faster or slower device.
