Problem with insert

<span style="font-size: 9pt; font-family: Arial">Hello,<br /><br />We have a Postgresql 8.1.8 and a problem, probably no bug.<br />But&nbsp;we must go in production tomorrow and we don&#39;t know where to look to solve this. Therefore I hope somebody can help us.<br /><br />The problem is when we insert with a function, we get the message <br /><br />SQLSTATE = 25P02<br />Error while executing the query;<br />ERROR:&nbsp; current transaction is aborted, commands ignored until end of transaction block</span><span style="font-size: 9pt; font-family: Arial">No changes made to database.</span><span style="font-size: 9pt; font-family: Arial">execute public.spr_ins_brieflayout <br /><br />When we do the insert directly again&nbsp;it goes fine, very strange. Other functions are going good, insert, update and delete.<br /><br />This is the function, other functions like this one goes perfect? Does anybody have an id&eacute;e where we have to look, to solve it.<br /><br />CREATE OR R!
