PostgreSQL is one of the best database engines for an average web project and many who moves to psql from mysql (for example) often ask the following questions: what is the analog of “show tables” in postgres? or how can I get the list of databases in postgres like “show databases” in mysql? The answers are short:
mysql: SHOW TABLES
postgresql: \d
postgresql: SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';
mysql: SHOW DATABASES
postgresql: \l
postgresql: SELECT datname FROM pg_database;
mysql: SHOW COLUMNS
postgresql: \d table
postgresql: SELECT column_name FROM information_schema.columns WHERE table_name ='table';







COOL! please add more!
While most would agree that this seems to be the endall stratagem, it is only a starting point with endless possibilities. ,

Actually, this is a terrible way to do the SHOW TABLES/COLUMNS/WHATEVER commands. Here is a great example: ME!
Where I work, I have no privileges on the database other than on a test database where I do my work. Even on there though I have limited privileges. Throw into this conundrum the fact that I’m trying to document the layout of all of the tables (something that has never been done here) and you suddenly get disaster. I can not log directly into the databases – I have to go through their command interpreter. Thus, I can not do the \dX options at all because I have no command line interface. If Postgresql had the SHOW XXX commands, then I could still get the layout of the tables. Because PSQL doesn’t have the SHOW XXX commands – I can’t do this. Wish it had it.

Mark, you can use the SELECT … form.
SELECT table_name FROM information_schema.tables WHERE table_schema = ‘public’;
and utilised to create a rustic

TQ for this info … I currently doing a number of these suggestions but there are many others might be new to us

Excellent blog site, mate! Postgresql: show tables, show databases, show columns – Linux * Screw is basically a thing. I am launching my very own shortly i will certainly backup elements of the one you have, legally needless to say
Thanks
