I dunno, before Postgres, Oracle was kind of the only game in town for that particular genre of RDBMS. I'm sure you can rattle off a dozen other systems that hit some of the featuresets (or even most), but even today, Oracle is really the most straightforward, in-house scalable RDBMS platform that you can actually hire folks with experience on, isn't it?
It's hard enough finding Postgres SAs these days as it is!
Not really. I get emails occasionally from people looking for PostgreSQL staff.
Generally I try and steer them to either the PostgreSQL jobs mailing list (https://www.postgresql.org/list/pgsql-jobs/), or if they have specific needs then I'll steer them to appropriate people (if known).
Of the people that contact me... some are Weird (not in any positive way). When I ask them how much they're looking to pay (even roughly), they either avoid answering that point, go silent completely, or just do other strange stuff.
Those ones don't get put in contact with anyone. Not sure what they think they're doing, but wasting people's time isn't on.
This assumes a level market with even distribution of information and power. Companies pay as little as they can get away with, not what the job is worth.
