Web Links Fails to Install on D7.7 (PostgreSQL)

Issue Summary

The Web Links 7.x dev version apparently does not make appropriate calls to the database abstraction layer. For those of us using PostgreSQL, the install function fails on creating the table weblinks. What it does it try to create the fields last_clicked and last_checked with a field type of datetime. datetime doesn't exist in PostgreSQL. The correct field type is timestamp. I'm thinking that, if it's properly implemented, Web Links should not have to deal with this; it should be taken care of by the abstraction layer. (It may be that I'm too used to CakePHP's abstraction layer which makes all this a slam dunk, and too new to Drupal's abstraction layer.)

Anyway, before you say, "So, who's using PostgreSQL, anyway?!", remember, we're out there, as well as other database users not on MySQL. Don't forget us. (Actually, I was a MySQL/InnoDB user but got tired of "MySQL server has gone away." I said, "If it wants to go away, let it go away." PostgreSQL doesn't do that.)
