This came up back on August 9th 2020 in #lobsters on freenode. They were doing a system upgrade and providing a report by using `watch` to `cat` together a HTML header and footer with `mysql -e ‘select * from information_schema.processlist’` to provide a status report. Thought that was a neat hack.
I wanted to know what the analogue for MySQL ‘show tables’ was in PostgreSQL, and I found the answer, use the information_schema, here:
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'; mysql: DESCRIBE TABLE postgresql: \d+ table postgresql: SELECT column_name FROM information_schema.columns WHERE table_name ='table';
