The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/9.1/static/queries-with.html
Description:
Na documentação mostra uma migração do oracle para o postgresql no qual
utliza a função nativa "instr". Na documentação mostra que esta função
existe no postgresql, porem quando tento utilizar me retorna erro dizendo
que nao existe.

Aline, esta lista utiliza inglês como língua principal.
Sobre a sua dúvida, a documentação [1] é bem clara quando diz que o
postgres *não* tem tal função mas que você pode criá-la se quiser (há
uma seção [2] com tal implementação em PL/pgSQL).
"Example 42.10 shows how to port a function with OUT parameters and
string manipulation. PostgreSQL does not have a built-in instr
function, but you can create one using a combination of other
functions. In Section 42.12.3 there is a PL/pgSQL implementation of
instr that you can use to make your porting easier."
