Question

我知道\ d仅适用于psql，我可以使用psql -E查看用于实现的实际SQL查询是什么\ d

这是我的例子

\d foo_table
********* QUERY **********
SELECT c.oid,
  n.nspname,
  c.relname
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relname ~ '^(foo_table)$'
  AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 2, 3;
**************************

********* QUERY **********
SELECT c.relchecks, c.relkind, c.relhasindex, c.relhasrules, c.relhastriggers,        
c.relhasoids, '', c.reltablespace
FROM pg_catalog.pg_class c
 LEFT JOIN pg_catalog.pg_class tc ON (c.reltoastrelid = tc.oid)
WHERE c.oid = '16386'

**************************

********* QUERY **********
SELECT a.attname,
  pg_catalog.format_type(a.atttypid, a.atttypmod),
  (SELECT substring(pg_catalog.pg_get_expr(d.adbin, d.adrelid) for 128)
   FROM pg_catalog.pg_attrdef d
   WHERE d.adrelid = a.attrelid AND d.adnum = a.attnum AND a.atthasdef),
  a.attnotnull, a.attnum
FROM pg_catalog.pg_attribute a
WHERE a.attrelid = '16386' AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
**************************

********* QUERY **********
SELECT c.oid::pg_catalog.regclass FROM pg_catalog.pg_class c, pg_catalog.pg_inherits i 
WHERE c.oid=i.inhparent AND i.inhrelid = '16386' ORDER BY inhseqno
**************************

有多个查询，其中一些以“;”结尾其中一些不是。我完全糊涂了。我应该在PHP中使用什么查询来执行与“\ d”相同的操作？

幸运的是，我找到了答案。 http://www.linuxscrew.com/2009/07/03/postgresql-show-tables-show-databases-show-columns/

使用php查询\ d <table name =“”> </table>
