+1.  I know I've used worker_spi as a reference for writing background
workers before.

IMHO it'd be better if the patch documented the places where the ordering
really does matter instead of hoping extension authors will understand the
reasoning behind the proposed reordering.  I agree that the current code
could lead folks to think that PushActiveSnapshot must go after
SPI_connect, but wouldn't the reverse ordering just give folks the opposite
impression?
