That assumes the line already exists. I think this does what most people
want:

    AppendIfNoSuchLine "com.foo.bar.jdbc.url=gak"
    SplitOn = ( = )
    SetLine "com.foo.bar.jdbc.url=pgsql:somehost:5432:user"
    ReplaceLinesMatchingField "1"

Also, since SplitOn must be a single character, it does not work for
assignments that use more than one character, such as " = " or ":=" .
