Pg_Tablespace_Location

Use pg_tablespace_location (tablespace_oid)(PostgreSQL 9.

2+) to get the path in the file system where the tablespace is located.

You’ll get oid of tablespace from pg_tablespace, so the query should be.

select spcname , pg_tablespace_location (oid) from pg_tablespace;, PostgreSQL creates pg_default and pg_global when you create a cluster, perhaps by using initdb directly.

The initdb utility can take an argument that sets the data directory, but no arguments about where to put the pg_default and pg_global tablespaces.

I’d conclude they’re always created in the data directory.

I could easily be wrong about that.

I don’t think they can be moved.

Tablespaces.

Tablespaces in PostgreSQL allow database administrators to define locations in the file system where the files representing database objects can be stored.

Once created, a tablespace can be referred to by name when creating database objects.

By using tablespaces, an administrator can control the disk layout of a PostgreSQL installation.

, pgDash is an in-depth monitoring solution designed specifically for PostgreSQL deployments.

pgDash shows you information and metrics about every aspect of your PostgreSQL database server, collected using the open-source tool pgmetrics.

, 14/03/2020 There often is a discussion if tablespaces should be used in PostgreSQL.

People used to work with Oracle are often a bit surprised by this discussion as there is no way around using tablespaces in that technology.

PostgreSQL does not force you to use tablespaces at all and I am pretty sure that there are plenty of PostgreSQL installations out there that do not use them and never even.

, Tablespaces in PostgreSQL allow database administrators to define locations in the file system where the files representing database objects can be stored.

Once created, a tablespace can be referred to by name when creating database objects.

By using tablespaces, an administrator can control the disk layout of a PostgreSQL installation.

This is useful in at least two ways.

, Tablespaces are designed to allow Postgres clusters to be spread across multiple storage devices.

Create tablespace creates a symbolic link in the pg_tblspc directory in the cluster’s data directory pointing to the newly-created tablespace directory.

Unfortunately, though there is a command to move tables and indexes between tablespaces, there is no command to move tablespaces to different.

, Summary: in this tutorial, you will learn how to remove a tablespace by using the PostgreSQL DROP TABLESPACE statement.

Introduction to DROP TABLESPACE statement.

To remove a tablespace, you use DROP TABLESPACE statement as follows:, location for pg_default tablespace.

I am new at Postgresql.

Previously I used to work with Oracle.

I am surprised to see that the location for pg_default tablespace in my database for a Postgresql.
