For the last few years, I’ve believed that there was no way to get the column names of tables using the db interface. Today I discovered that—using both postgresql and sqlite3, at least—I can extract these from the “name” fields of the “headers” field of the row-response to a “SELECT * FROM table_name LIMIT 0;”. The documentation suggests that these header fields are fragile and undocumented… but it would be nice to have known that it was there. Would it make sense to add a library function that returns column name information if it’s available, or at least add some sample code to the documentation?
