postgresql-15-prefix binary package in Ubuntu Lunar s390x

 This PostgreSQL module provides the prefix_range datatype, allowing to
 index searches such as finding the longest prefix matching a telephone
 number, having prefixes in a table and telephone number as a parameter:
 .
  select * from prefixes where prefix @> '0100091234';
 .
 The prefix column has to be of type prefix_range, and any text field
 can get indexed by the provided GiST opclass.
