Dear Cristian, If you need to index the field, you must know that it limit the length up to 1000 bytes. So if you need to index the field you must limit the field type, ex: varchar(250), than you can index the field and you can gain better perfomance in searching base on the fields, because the search uses the index you have been created. If you do not need to index the field, you can use the text field. Because text field can store data up to 4 Gbytes.

Hello, just a little question, It's preferable to use Text Fields or varchar(255) fields in a table? Are there any performance differences in the use of any of them? Thanks a lot for your answer! ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
