I would like to suggest a upgrade from the brazilian translation file. It's current release data are old, and deprecated (at 4.2.2). I have posted a message at "phppgadmin-lang" forum, at SourceForge.net project website [https://sourceforge.net/forum/forum.php?thread_id=3297166&forum_id=124291].
I have already contacted Ângelo Rigo (the maintainner, information presented at the header "portuguese-br.php" file phpPgAdmin language file), and told him yesterday about this issue.
A little workaround i made (but not at the "recoded" string encoding file, just at the "lang" root path), and maybe can help you some way.
Anyway, i do suggest a complete review from this translation, intending to really matching the "english.php" main file with the brazilian translation.
If help is needed, i can do it.
