How to assign variable values in v_message in Function 2 and pass to function 1. How can I do this? Instead of COLUMN1,OLDVALUE1,NEWVALUE1 it should take variables assigned.
In pure sql I would do:
ARRAY[col1, col2, col3]::type[]
To create an array using column references as inputs instead of literals.
Likewise, for a composite type:
(co1, col2, col3)::type
You will probably need to use those constructs as fragments in your pl/pgsql code to build up the array of composites from variables/columns as opposed to trying to write a text literal.
If you want to write a literal, though, you may find the format() function to be helpful (and a sight easier to read, and generally safer, than string concatenation, which would be your option of last resort.
