Description:
------------
I found that pg_meta_data do not returns fields descriptions in result. I explore sources and found that table's meta fteched by query, citated below. I do not have free FreeBSD host for programming experiments, but i upgrade a query little bit, adding ability to fetch description from fields.

Can you use my query to add to pg_meta_data() ability to return field descriptions?

Reproduce code:
---------------
Original code:
        smart_str_appends(&querystr,
                        "SELECT a.attname, a.attnum, t.typname, a.attlen, a.attnotNULL, a.atthasdef, a.attndims "
                        "FROM pg_class as c, pg_attribute a, pg_type t "
                        "WHERE a.attnum > 0 AND a.attrelid = c.oid AND c.relname = '");

        tmp_name = php_addslashes((char *)table_name, strlen(table_name), &new_len, 0 TSRMLS_CC);
        smart_str_appendl(&querystr, tmp_name, new_len);
        efree(tmp_name);

        smart_str_appends(&querystr, "' AND a.atttypid = t.oid ORDER BY a.attnum;");
        smart_str_0(&querystr);



Changed code, that i proposes:
        smart_str_appends(&querystr,
                        "SELECT a.attname, a.attnum, t.typname, a.attlen, a.attnotNULL, a.atthasdef, a.attndims, d.description "
                        "FROM pg_class as c JOIN pg_attribute a on (a.attrelid = c.oid) JOIN pg_type t on (a.atttypid = t.oid) "
                        "LEFT JOIN pg_description d on (d.objoid=a.attrelid and d.objsubid=a.attnum and c.oid=d.objoid) "
                        "WHERE a.attnum > 0  AND c.relname = '");


        tmp_name = php_addslashes((char *)table_name, strlen(table_name), &new_len, 0 TSRMLS_CC);
        smart_str_appendl(&querystr, tmp_name, new_len);
        efree(tmp_name);

        smart_str_appends(&querystr, "' ORDER BY a.attnum;");
        smart_str_0(&querystr);


Expected result:
----------------
Information about table, including fields description (aka comments).

Actual result:
--------------
No any descriptions :(
