Briefly, you use the special pg_ tables [0].
The following query is probably not the most efficient way of doing it,
but it shows the column names for the "wines" table. The first seven
listed are system columns (tableoid - ctid), and the rest are data
columns (name - score).
You can look at the descriptions for each of the pg_ tables to refine
your query a bit, exclude system columns, figure out data types, and so
forth.
cww=# SELECT pg_class.relname, attname FROM pg_attribute, pg_class WHERE
attrelid = pg_class.reltype::integer - 1 AND pg_class.relname = 'wines'; relname | attname
---------+----------------- wines | tableoid wines | cmax wines | xmax wines | cmin wines | xmin wines |
oidwines | ctid wines | name wines | vintage wines | origin wines | specific_origin wines | color wines |
typewines | description wines | vintner wines | entry_date wines | score
(17 rows)
This query works on 8.1.9.
