There&apos;s things where relational databases are a good fit, and things that are a bad fit. As such, this isn&apos;t about what PostgreSQL does poorly, but about the cases where a key-value store with some pretty good data structures comes in handy. Would you really store temporary data in your relational database? Would you use it as a caching mechanism? Perhaps as a queue? Not unless you&apos;re crazy. So I guess this isn&apos;t about what PostgreSQL performs poorly, but about where Redis is a better solution.</text><parent_chain><item><author>seunosewa</author><text>Really?

It&apos;s just a bunch of C files with no real external dependencies (I don&apos;t even have to run ./configure before building it!).&lt;p&gt;Operationally, for a generic non-db-expert kind of person like me, redis is much simpler to manage than PostgreSQL.  With redis I don&apos;t need to worry about vacuuming, write ahead logs, archiving, query tuning &amp;#38; statistics, lock management, etc (to name a few things from the config file).</text><parent_chain><item><author>seunosewa</author><text>Really?
