postgres sql assistance

Dear all,

I am an accidental postgres DBA and learning things every day. Apologies
for my questions if not properly drafted.

I am trying to load data from the temp table to the main table and catch
the exceptions inside another table.

temp table is cast with the main table data type and trying to load the
data.

temp table is below.

category_name | description
| is_active
-------------------------------------------+---------------------------------------------+-----------
*Tech123212312312323233213123123123123 *| Furniture and home decor
| true
*Tech123212312312323233213123123123123 *| Electronic devices and
accessories | true
Elec | Books of various genres
| *15*
TV | Books
| *12*
cla | Apparel and fashion accessories
| true

category name is varchar(25) and is_active is boolean in main table. So i
should get exceptions for 1st,2nd for category_name rows and 4 and 5th rows
for boolean. In exception table results,its only showing

Exception table is below. Here instead of showing exception for value 12 in
the is_active table its showing old exception for 15 itself.. Script is
attached,,...SQLERRM value is not getting updated for row 12..WHat could be
the reason for this?

value too long for type character varying(25) category_name 1 2024-01-16
16:17:01.279 +0530 value too long for type character varying(25)
