We can use two modes in PGCLI prompt, one is the Emacs mode which is the default one and the other is Vi-mode for Vim fanboys. ![]() We can even use j and k for moving vertically in an output table. We get an excellent table display of output which we can view by scroll or arrow keys. There are a lot of ways pgcli can be installed, my preferred way is with pipx, it just works well and you don't have to install it every time or mess up your global python packages environment.Įnter fullscreen mode Exit fullscreen mode The package acts as a CLI for accessing and executing any SQL queries, so we can simply provide the options/parameters to plug the database in and access the schema and its related data. PGCLI allows us to interact with any Postgres database via the command line, it can be a remote database or a local database, you can access it right away from your terminal. PGCLi is a python package that acts as a CLI for executing SQL queries in a Postgres database. This article will cover the basics of using the PGCLI tool to perform simply as well as advanced options in interacting with your Postgres database. If you are like CLIs and love to play with backend systems like Postgres(database) then chances are you will love this article. We can simply execute SQL queries in a PSQL-like shell with additional features like autocompletion, text-editing modes, file input/output options, etc. It's PGCLI, that can act as an editor window for writing SQL queries for Postgres Databases. If so, connection string parameters will override any conflicting command line options.Have you ever used the Postgres database and did you know you don't have to launch PGAdmin every time you want to write SQL queries, you can write down those queries even inside a terminal with a python package. If not specified, the postgres database will be used if that does not exist (or if it is the name of the new database being created), template1 will be used. Specifies the name of the database to connect to when creating the new database. In some cases it is worth typing -W to avoid the extra connection attempt. However, createdb will waste a connection attempt finding out that the server wants a password. This option is never essential, since createdb will automatically prompt for a password if the server demands password authentication. Wįorce createdb to prompt for a password before connecting to a database. This option can be useful in batch jobs and scripts where no user is present to enter a password. pgpass file, the connection attempt will fail. If the server requires password authentication and a password is not available by other means such as a. Specifies the TCP port or the local Unix domain socket file extension on which the server is listening for connections. If the value begins with a slash, it is used as the directory for the Unix domain socket. Specifies the host name of the machine on which the server is running. The options -D, -l, -E, -O, and -T correspond to options of the underlying SQL command CREATE DATABASE see there for more information about them.Ĭreatedb also accepts the following command-line arguments for connection parameters: Show help about createdb command line arguments, and exit. (This name is processed as a double-quoted identifier.) -V Specifies the template database from which to build this database. See CREATE DATABASE STRATEGY for more details. Specifies the database creation strategy. (This name is processed as a double-quoted identifier.) -S template Specifies the database user who will own the new database. Specifies the locale provider for the database's default collation. Specifies additional collation rules to customize the behavior of the default collation of this database. Specifies the ICU locale ID to be used in this database, if the ICU locale provider is selected. Specifies the LC_CTYPE setting to be used in this database. Specifies the LC_COLLATE setting to be used in this database. Some locales are only valid for ICU and must be set with -icu-locale. This is equivalent to specifying -lc-collate, -lc-ctype, and -icu-locale to the same value. Specifies the locale to be used in this database. The character sets supported by the PostgreSQL server are described in Section 24.3.1. Specifies the character encoding scheme to be used in this database. (This name is processed as a double-quoted identifier.) -eĮcho the commands that createdb generates and sends to the server. Specifies the default tablespace for the database. ![]() ![]() Specifies a comment to be associated with the newly created database. The default is to create a database with the same name as the current system user. The name must be unique among all PostgreSQL databases in this cluster. Specifies the name of the database to be created. ![]()
