Pg_database catalog table is very important to fetch the information related to all the databases.īelow is an example of a list of the databases. We can also use limited options to list the database by using the pg_database catalog table.We can list the database by using shell prompt as well as using database shell prompt in PostgreSQL.Using the above command, we have a list system as well as user-created databases.We can use the metadata command and pg_database catalog table to list the databases in PostgreSQL.Basically, we have using the below command to list all the databases is as follows.In the second example, we use db_test user to list databases using db_test user, it’s possible to list the databases in PostgreSQL because we do not need to be given any privileges to list the databases in PostgreSQL.In the above first example, we have checked the privileges of the user the db_test user doesn’t have any privileges on the database server.The below example shows that we do not need to provide any privilege to list database for user in PostgreSQL.To list the databases in PostgreSQL, we do not need to provide any privileges to the user any user can list the databases in PostgreSQL.We can list the databases are as follows.Pg_database –This is a catalog table of PostgreSQL that contains the information of all the database created by the user and contains the information of system databases.We can select a single or all column which was we want to display in the output. Name of the column –This is defined as the name of the column for the table of pg_database.We can select specific or all column from the table to see the list of databases in PostgreSQL. Select –This operation is used to select a column from the pg_database table to list the databases.This command is used to list all databases with information of database name, owner of the database, encoding, collate, ctype and access privileges of the database, size of the database, database tablespace name, description for the database, encoding, collate, ctype and access privileges for the databases. \list – This command is the same work as \l command in PostgreSQL.This command is used to list all databases with information of database name, owner of the database, encoding, collate, ctype, and access privileges of the database. ![]() \list –This command is the same work as the \l command in PostgreSQL.\l – This command is used to list all databases with information of database name, owner of the database, encoding, collate, ctype and access privileges of the database, size of the database, database tablespace name, and description for the database.\l –This command is used to list all databases with information of database name, owner of the database, encoding, collate, ctype, and access privileges of the database.Hadoop, Data Science, Statistics
