As mentioned by you offlist that you are not able reproduce this
issue, I have tried again and what I observe is that I am able to
reproduce it only on *release* build and some cases work without
this issue as well,
example:
./vacuumdb --analyze-in-stages -t t1 -t t2 -t t3 -t t4 -t t5 -t t6 -t t7 -t t8 -j 8 -d postgres
Generating minimal optimizer statistics (1 target)
Generating medium optimizer statistics (10 targets)
Generating default (full) optimizer statistics
So to me, it looks like this is a timing issue and please notice
why in error the statement looks like
"ANALYZE ng minimal optimizer statistics (1 target)". I think this
is not a valid statement.
Let me know if you still could not reproduce it.
