Sorry to raise the issue on startup_cb. I added a whole bunch of logging
statements and I was only running the section of code I wanted when the
startup callback had options.
This now gets me to the next issue I encounter. In my output plugin, I'm
trying to use the SPI interface to query about PostGIS OIDs in the startup
callback. Just calling SPI_connect() seems to be causing a segfault.
This is the last thing I see in the logs before the segfault occurs:
