OK, I looked at this a bit, and the answer is that load_libraries uses
SplitIdentifierString, ie, it thinks the value of the variable is a list
of comma-separated SQL identifiers. So if you want a
filename containing upper case, whitespace, or commas, double-quote it.
That might seem a bit bizarre, but because of the special meaning of
commas we'd need some quoting rule anyhow. I'm not sure it's worth
making local_preload_libraries have its own private parsing convention.
Perhaps this is just a documentation deficiency.
