 Are all chars  in your query LATIN1  symbols and are you  sure that all
 used  chars  have counterpart  in  ASCII? For  this to_ascii()  support
 LATIN1, LATIN2  and WIN1250 only. I'm  not sure if  there is a  way how
 convert others special chars (for example some Asiatic encodings).

 # show server_encoding;
 server_encoding 
 -----------------
 LATIN1

 # show client_encoding;
 client_encoding 
 -----------------
 LATIN1

 # SELECT '>>' || TO_ASCII('ÁÉÍÓÚáéíóú??°') || '<<';
     ?column?      
 -------------------
 >>AEIOUaeiou?? <<
 

 The last char  in the string is dec 176 (hex 0xB0). Which  char do you
 expect after conversion to ASCII (0-127)?
