Delete a Postgres User with DependenciesĪttempting to remove a Postgres user with dependencies fails and shows an error. The removed users are no longer on the list. Recheck the user list to confirm all the roles are deleted: \du Add IF EXISTS to skip users that are not available.Ĥ. The command removes multiple roles at once. Delete multiple Postgres users by separating individual users with a comma: DROP USER. Locate the users for deletion and use the names in the following step.ģ. Connect to the PSQL client with: sudo -u postgres psql
The instructions below explain how to connect to the PostgreSQL client and delete multiple users.ġ. The PSQL client allows deleting more than one Postgres user at once. This output indicates a successful deletion. The user is no longer on the list of roles. Display the user list again to confirm the user is gone: \du Note that some tools do not change the character-set or newline of an existing file, or require that you choose a menu item to make the change happen.The client notifies if the role is nonexistent.Ĥ. You may want to change the default to Linefeed for the Unix convention.
There are many other SQL tools that run on Mac OS X, especially the Java-based tools using JDBC. Or to get more information on tables in the current database: dt+. Other Java-based IDEs are free-of-cost, run well on Mac OS X, and include SQL editing tools: IntelliJ, NetBeans, Eclipse. TextWrangler's commercial big-brother BBEdit is also a popular text-editor on Mac OS X. Other good text editors include JEdit (Java-based, free-of-cost), TextWrangler (free of cost), and BBEdit. My usual choice in text editors is TextMate, running the surprisingly productive "Zenburnesque" Fonts & Color scheme in Preferences, where you can force the text to be interpreted as SQL without bothering to save the file by choosing "SQL" from the popup at the window's bottom frame. Then I paste the SQL back into a SQL window in pgAdmin to execute. When creating a new table, I copy the SQL from a similar table, paste into a text editor, and edit appropriately. Nowadays I take advantage of the feature where pgAdmin generates and shows you the SQL that would re-create the table on which you've clicked. When first starting out creating tables, I used the GUI dialogs in pgAdmin. This issue has been acknowledged in the mailing lists.īut otherwise, pgAdmin has served me well for connecting to the Postgres server, creating databases, creating tables, creating columns, creating a few initial rows of data, editing some field values, and so on. This is not easy to do as a Mac GUI user. You'll have to gain access to the filesystem as the Postgres superuser (usually that's the Unix user 'postgres'), and edit the file. To the user, it seems the rule you entered simply vanished. (a) You won't realize you saved incorrect syntax. Unfortunately, pgAdmin does NOT parse the entries when entering or saving them. When loading a saved conf file with incorrect syntax (usually I forget to put the slash+number on an IP address such as 127.0.0.1/32), pgAdmin parses the file, identifies the flaw, and chooses to ignore the rule by not displaying it.
It looks goofy from a Mac aesthetics perspective, but it works. But pgAdmin has worked nearly flawlessly for me. Surprising because I have a knack for breaking/corrupting/crashing nearly every developer tool I start using as a newbie. If you have already used Toad, u would like to check it.īeing new to SQL (but old to other relational databases) and a Mac guy, I have found pgAdmin to work surprisingly well. psql & text editor of choice (if so, which one?) > Coming from an Oracle world, I'm thinking of toad, sql developer, etc.
> terms of writing sql (ddl, dml & pg/plsql), what tools are I have a postgres 9.1 database up & running, no problem.
