Thread: pgsql: Parse catalog .dat files as a whole when compiling the backend

Parse catalog .dat files as a whole when compiling the backend

Previously Catalog.pm eval'd each individual hash reference
so that comments and whitespace can be preserved when running
reformat-dat-files. This is unnecessary when building, and we can save
~15% off the run time of genbki.pl by simply slurping and eval'-ing
the whole file at once. This saves a bit of time, especially in highly
parallel builds, since most build targets depend on this script's outputs.
