Subject: Install a workaround for 'TeX capacity exceeded' problem
X-Git-Tag: REL9_0_BETA1~7
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=a5ec86a7c787832d28d5e50400ec96a5190f2555;p=postgresql.git

Install a workaround for 'TeX capacity exceeded' problem
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.
