Version

I was doing a small “quick” data transfer between two servers. The source was 19c and the destination was 18c, so I used the VERSION parameter during the export.

expdp … version=18 directory=…

The export went fine, but when I started the import I immediately got this error.

ORA-39002: invalid operation

A little Googling and I came across MOS Doc ID 2482971.1. In short, the time zone file was different between the two databases.

I’m looking forward to the Seattle PostgreSQL User Group meetup this Thursday (June 20, 2019) at 5:30pm! We’re going to get an early sneak peek at what’s coming later this year in PostgreSQL’s next major release. The current velocity of development in this open source community is staggering and this is an exciting and valuable opportunity to keep up with where PostgreSQL is going next.

One thing that’s a bit unusual about this meetup is the new location and late timing of the announcement. I think it’s worth a quick blog post to mention the location: for some people this new location might be a little more accessible than the normal spot (over at the Fred Hutch).
