"A thread at the Ubuntu forms (post #15) indicates that this is a problem for Upstart 0.6.3-11, and have been successful with Upstart 0.6.3-10. Excerpt:
On the 20th I innocently upgraded the packages suggested by the Update Manager. Next day upon re-boot I found that Apache and Postgresql no longer started. Solution: downgrade Upstart 0.6.3-11 to 0.6.3-10. Apache and Postgresql work normally now. How? Using the Synaptic Package Manager search for upstart. Select it and then under Package click on Force Version. You get to choose between 0.6.3-11 and 0.6.3-10. Choose 10 and click on apply."
