I felt like the talk was too technical. Simply showing us all the different datatypes, how they look in a query and what raw result they return does not convince me of using Postgres. As asked at the end of talk: it was also not clear what the difference was between the different datatypes was. It would be more interesting to see usage examples that demonstrate their power (maybe compared to MySQL?).
Stephan should also try and look more at the crowd and less at the slide projection behind him. There was at least one instance where someone from the crowd tried to ask a question but it was not noticed.
Not an area I know a lot about but I found it to be an interesting talk. As a beginner it was nice to see the various data types available in postgresql and noting how to work with them. Would have been nice to see a valid use case for picking a particular datatypes or the pros/cons of each datatype.

Very good talk, stuff was clearly explained. Learned a lot as someone who had little clue about ProstgreSQL. It''s true that there could have been more use case examples. You gave one with the array data type - more of this!
Anecdotal remark: you say "may or may not" a lot :)
Clearly I expected something else by the title of this talk. It's not per se a bad thing, but the talk consisted more of a listing of (to me) a few gimmicks in PostgreSQL which could be used to store some nonrelational data.
The content was of a good level and very complete in its presentation, but it didn't help me with the thought if postgreSQL is a good replacement for so structures we're currently storing in MongoDB.
Good detailed talk, just showed how PostgreSQL is capable of some NoSQL aspects.
For some datatypes I missed in the impact on performance, I was particularly interested if some example queries would use indexes.
Glad to have (lots) of concrete examples on how to use these "less usual" datatypes.
I could also use a typical use case to walk through all the different approaches.
And more importantly a summary of pro/cons of the data types usages especially with index support/performance.
This may or may not be a good talk :) try to use those words a bit less, although it is fun when you're trying to make a drinking game out of it. The talk itself was pretty technical with lots of functions. But it explained to me very well what Postgres has to offer, so I found it very interesting.
Great technical talk, especially for a novice in Postgres. As stated before, the presentation showed exactly what it has to offer in dealing with schema-less data. I personally missed the 'why choose Postgres' part though. Could be a wrong expectation on my part though.
It felt like a presentation on the manual of PostgreSQL. Nothing more.
I expected a more high level talk on the extras (functionality, performance, ...) PostgreSQL can provide in comparison to MySQL, Mongo, etc.
Most questions after the talk couldn't really be answered either.
This talk won't help more people to adopt PostgreSQL I'm afraid. Maybe future presentations can contain examples of real-life implementations and the type of projects where PostgreSQL can/will/should be used.
Reading the previous comments, i think the talk was not that bad actually. A bit on the dry side, and missing some insight about performance and other real world applicability. But i would have spent a LOT more time than that talk to figure all this out just from the postgres manual. The talk achieved explain the context and compared the different options and told what is possible and what not.
I'm absolutely new to NoSQL in general, seeing this made me realise how impressive it can be.
I'd love to see Stephan keep in touch with the audience a bit more as in more eye contact across the whole audience every now and then. Other than that I think it was a good presentation.
Title of talk was misleading. Would have loved to hear why I should choose for PostGres, when I should choose a NoSQL datastore and when a relational store. The sql syntax I can look up on the internet.

@lig: I just fixed the spelling error. Thanks for letting me know.

I should've browsed the PostgreSQL documentation for 15 minutes instead of attending this talk.
Thank you for your feedback. Could you give me some more hints about what was missing or what you expected from the talk?
