pgsql: Unwind some workarounds for lack of portable int64 format specif

Unwind some workarounds for lack of portable int64 format specifier

Because there is no portable int64/uint64 format specifier and we
can't stick macros like INT64_FORMAT into the middle of a translatable
string, we have been using various workarounds that put the number to
be printed into a string buffer first. Now that we always use our own
sprintf(), we can rely on %lld and %llu to work, so we can use those.

This patch undoes this workaround in a few places where it was
egregiously verbose.
