I am starting to agree that our \d* handling is just too overloaded.
Look at the option list from \?:
Informational
\d [NAME] describe table, index, sequence, or view
\d{t|i|s|v|S} [PATTERN] (add "+" for more detail)
list tables/indexes/sequences/views/system tables
\da [PATTERN] list aggregate functions
\dc [PATTERN] list conversions
\dC list casts
\dd [PATTERN] show comment for object
\dD [PATTERN] list domains
\df [PATTERN] list functions (add "+" for more detail)
\dg [PATTERN] list groups
\dn [PATTERN] list schemas
\do [NAME] list operators
\dl list large objects, same as \lo_list
\dp [PATTERN] list table access privileges
\dT [PATTERN] list data types (add "+" for more detail)
\du [PATTERN] list users
\l list all databases (add "+" for more detail)
\z [PATTERN] list table access privileges (same as \dp)
Can anyone remember all those? With the single-letter options, once the
list got too long, we started encouraging long option names. It seems
the same is true of \d.
I like the idea of adding a new syntax to show that information using
simple SQL command syntax, and putting it in the backend so all
applications can access it. I know we have information schema, and
maybe that can be used to make this simpler.
