when building PDF output for recent versions of the documentation.
There is probably a better answer out there somewhere, but
we need something now so we can build beta releases.

+% This file redefines FlowObjectSetup to eliminate one of the two control
+% sequences it normally creates, thereby substantially reducing string usage
+% and permitting the complete Postgres documentation to be built without
+% overflowing a hard-to-expand TeX limit.  The only known penalty is an
+% increased number of TeX warnings about ignoring duplicate definitions.
+%
+% Curiously, we only see the failure when building PDF output --- plain PS
+% output does not come anywhere close to overflowing the string table.
+% There may be another solution hidden in that observation.
