Subject: [NOVICE] Migration from MySQL, some difficulties with
DESCRIBE and SHOW
I'm unfamiliar with mysql,
but I think what you are looking for in the psql client are these commands

SHOW TABLES:

\d{t|i|s|v}... list tables/indexes/sequences/views

\d will give a list of all of these objects
\dt will give a list of only tables

mfx=# \d
List of relations
Name | Type | Owner
------------------+----------+---------------
accent | table | Administrator
accenttype | table | Administrator
actor | table | Administrator
actor_id_seq | sequence | Administrator
actoraudio | view | Administrator
audio | table | Administrator
audiotype | table | Administrator
(7 rows)

DESCRIBE: (I'm assuming this gives a listing of a table's structure)

\d tablename

mfx=# \d accent
Table "accent"
Column | Type | Modifiers
------------+-------------------+-----------
accenttype | character varying | not null
id | integer | not null
Primary key: accent_pkey
Triggers: RI_ConstraintTrigger_1673596,
RI_ConstraintTrigger_1673602

Hope this helps
