Esteemed Monks,

I wrote a Perl program wich uses PostgreSQL. This program was running well for months until yesterday, when my SysAdmin upgraded the DBD::Pg module for the current version (1.40).

Now, where I have 

my $sql = "
 LOCK TABLE tabreserves IN SHARE MODE;
 SELECT 
  tabreserves.date,
  tabreserves.hour_i,
  tabreserves.hour_e,
  tabreserves.idreserve,
  tabreserves.fk_idfield,
  tabfields.imped,
  tabfields.design

  FROM tabreserves
  LEFT JOIN tabfields ON
   tabfields.idfield = tabreserves.fk_idfield
  WHERE date = ? AND (hour_i < ? AND hour_e > ?)
   AND (fk_idfield = ? OR ? = ANY (imped))
  LIMIT 1
";

[download]
Raises 2 errors:

1st 

DBD::Pg::st execute failed: ERROR:  cannot insert multiple commands in
+to a prepared statement

[download]

If I delete the first line LOCK TABLE tabreserves IN SHARE MODE;, raises another error.

2nd 

DBD::Pg::st execute failed: ERROR:  column "hour_i" is of type integer
+ but expression is of type character varying
HINT:  You will need to rewrite or cast the expression.

Needless to say that I have _many_ statements wich uses the same structure - e.g. multiple commands in a prepared statement and not casting expressions, since that wasn't mandatory before.

When we (me and the sysadmin) saw the errors we thought: "well... time to upgrade to PostgreSQL 8!". We were using 7.4. We did the upgrade. But the errors persist.

What am I missing here? Do I really need to cast expressions? and why can't I use multiple statements now?

Thanks,
Miguel
