Re: Implementation of Date/Time Input Interpretation

Thank you for your prompt reply.

I want to be able to, from my own script, determine if postgres will
be able to interpret a string as a date or time. If you can suggest a
better way of accomplishing this beyond reimplementing your algorithm
I would be happy to hear it!

Cheers,

Francis Markham
