Any stock utility is likely to make choices that are sub optimal for your needs. with 700 changeovers pending I would want complete control over how each column is handled. > 3.

(probably several megabytes like other text fields). Getting descriptions in the same same result set as column data is probably impractical (see length limit for a possible reason why this has not been implemented). fetching them separately en-masse and caching them or fetching or individually afterwards should not be greatly difficult, resultsets are returned with the column and table indicated. > 4.

I hear there are several, But I can't understand why someone would want to perform non-graphical tasks using a GUI. -- ââ 100% natural -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
