I couldn't replicate any problem.  I put 5000 copies of those two
statements into a file and set up half a dozen psql sessions
concurrently reading the file.  No errors.

If you can provide a complete, reproducible test case, I'll be glad to
look at it, but there's not enough information here to do anything ...
