Re: defining yuor own commands in PG ?

In psql, yes:

\set sel 'SELECT * FROM'
:sel clients;

\set desc '\\d'
:desc table

 

But what's wrong with "\d"? For me, its like the first thing people learn when practicing postgres.
It is even faster to type than DESCRIBE, right?

IMO, when you will bend postgres to mimick other DBMS, you will hide its real power from users.
