Comment (by pramsey):

 This is more specific than I thought. Using our Carto pgsql branch, which
 has a backport of the pg11 parallel "create table as" support in it, and
 changing to SPI_execute, causes a crash condition. Using generic pg10,
 there is no parallel mode, and no crash condition.
 Running the ST_Transform query without the "create table as" part causes
 **no problems** even when a parallel plan is used. So the problem is
 (currently) specific to the carto branch, but **might also** be something
 that is an issue in pg11 since that's where we pulled the "create table
 as" support from.

 Next test: on pg11 is this use case (parallel "create table as")
 problematic.
