pgsql: Review format of code generated by PerfectHash.pm

Review format of code generated by PerfectHash.pm

80f8eb7 has added to the normalization quick check headers some code
generated by PerfectHash.pm that is incompatible with the settings of
gitattributes for this repository, as whitespaces followed a set of tabs
for the first element of a line in the table. Instead of adding a new
exception to gitattributes, rework the format generated so as a right
padding with spaces is used instead of a left padding. This keeps the
table generated in a readable shape with its set of columns, making
unnecessary an update of gitattributes.
