Do you recommend PostgreSQL over MySQL?
A client would like to use a free database for an upcoming project.
My question is I wanted to give him the option of either MySQL or PostgreSQL. I'm familiar with both on usage from a code stand point but what benefits (if any) would one have over the other.
The project is a internal webservice (PHP/Python and maybe Java) but could be external if things go well enough.
I know this might be a subjective question but I'm looking for performance related answers or pitfalls that could arise by choosing one over the other. Or could this type of question be migrated to another site?
Thanks in advance for any advice
