i get the following python-error:

psycopg2.ProgrammingError: FEHLER:  Syntaxfehler bei »s«

LINE 1: ...dd_texts_to_item( 1234, ARRAY['PSYCOPG1', 'PSYCOPG2'] ); s s

But the created statement looks syntax-wise identical to the pgadmin-statement (except for the forced error of course):

select * from api_dev.add_texts_to_item( 444, array['PGADM1', 'PGADM2'] );

Try adding the following to your function to see what your function sees as being the value of the p_item_texts argument.

RAISE ERROR '%', p_item_texts;

I'm assuming that:

self.cur_.execute( sql, (doc_id, isins, ) )

performs dynamic string substitution as opposed to generating a prepared statement.  The placeholder values supplied to a prepared statement are treated as literals.

You may also want turn on statement logging in the server.
