Re^5: Posgres batch read with DBI? (updated)

my $dbh = connectpgdb(*,*,*,*,*);

... unmatched bracket error...

Just a total WAG, but if the quoted code was or was something like the actual code and not pseudo-code, remember that $, $) are Perl special (package-global) variables (see perlvar), so there are *, *) typeglobs of which they are subtypes (if that's the correct terminology).

my $dbh =
  # connectpgdb(*,*,*,*,*)   # syntax error
  # connectpgdb(*,*,*,*,*))  # syntax error
  # connectpgdb(*,*,)        # syntax error
  # connectpgdb(*)           # syntax error
  # connectpgdb(*,)  # compiles and runs
    connectpgdb(*))  # compiles and runs

while ($dbh) { print "foo \n";  $dbh = ''; }

sub connectpgdb { return $_[0]; }

^Z
foo

I can't duplicate the "unmatched bracket" error message you mention, but running under Perl version 5.30.3 vice 5.8.9 yields more error messages for my example code that are associated with the failed definition (hence absence) of $dbh, so maybe the "unmatched bracket" error is at the end of a long string | cascade of messages that begins with | stems from a syntax error.
(In the unlikely event you're running the actual code you posted. :)
