The flavor material is specific to the campaign setting, and Paizo tries to keep the core rulebooks as setting-neutral as possible. So that's why there isn't much written about the deities in the Core Rulebook.
There are several books that can grant more information:
The Pathfinder Chronicles: Gods and Magic book features two pages on each deity.
The Pathfinder Campaign Setting: The Inner Sea World Guide book features half a page on each deity.
About every third Adventure Path book features a 6-8 page article on one specific deity (spoilered below to avoid cluttering the page)
AP #2: Desna
AP #5: Lamashtu
AP #8: Abadar
AP #11: Zon-Kuthon
AP #14: Cayden Caelian
AP #17: Calistria
AP #20: Sarenrae
AP #23: Rovagug
AP #26: Iomedae
AP #29: Asmodeus
AP #32: Erastil
AP #35: Gorum
AP #38: Gozreh
AP #41: Nethys
AP #44: Pharasma
AP #47: Urgathoa
AP #50: Shelyn
AP #53: Irori
AP #59: Norgorber
AP #62: Torag
There are also non-core deities featured in some adventure path books, particularly after #62 (but also a couple prior to that).

The Pathfinder Wiki
has information about the deities of golarion online, but not as much as the articles in said adventure paths.

The Religion chapter in the World Guide is 22 pages long. The Core Rulebook already has close to 600 pages. There's simply not enough space to include all that. Besides, most players play in a pre-made setting, either Golarion with the deities printed in the World Guide or some other setting with its own gods. It wouldn't make much sense to print it twice.

I hear you Mulder's partner. Even with the wiki link above, the thing I find vexing is that there's no fluff in many of the deities of things like what their churches look like, or their shrines; how do their clergy dress and what are their titles?
But then there's the church of Pharasma. They build cathedrals, there are a couple examples of titles and hierarchy, and dress is suggested as well. Still vague enough for you to put a stamp on it for your campaign, but there you go.
Not surprisingly, Pharasma figures in strongly in my own homebrew. Its kind of a dark fairy tale theme, so the church of Pharasma doubles as "the church" in all those old Grimm's tales. Cold iron goes into a lot of Pharasmin objects, art, constructions and artifacts; also they incorporate images of roses (a bane to some of the unique creatures of my lands of Karnoss); and finally the dour but fair clergy tend to provide moral compass to an otherwise lawless land.
What kind of game are you running/playing? Maybe the community could help you create the fluff needed for the choices you're looking for.
