pgsql: Fix translate_columns[] arrays in opfamily-related psql function

Fix translate_columns[] arrays in opfamily-related psql functions

Make number of translate_columns elements match the number of output columns.
The only "true" value, which was previously specified, seems to be intended
for opfamily operator "purpose" column.  But that column has already translated
values substituted.  So, all elements in translate_columns[] should be "false".
