Tous les messages émis par le serveur PostgreSQL™ se voient affectés des codes d'erreur sur cinq caractères suivant les conventions du standard SQL pour les codes « SQLSTATE ». Les applications qui ont besoin de savoir quelle condition d'erreur est survenue devraient normalement tester le code d'erreur plutôt que de chercher le message d'erreur textuel. Les codes d'erreurs sont moins sujets à changement suivant les versions de PostgreSQL™ et ne sont pas sujets aux changements dûs à la localisation des messages d'erreur. Notez que seulement certains des codes d'erreur produit par PostgreSQL™ sont définis par le standard SQL ; quelques codes d'erreur supplémentaires pour les conditions non définies par le standard ont été inventés ou empruntés aux autres bases de données.
Suivant le standard, les deux premiers caractères d'un code d'erreur dénote une classe d'erreurs alors que les trois derniers indiquent une condition spécifique à l'intérieur de cette classe. Du coup, une application ne reconnaissant pas le code d'erreur spécifique pourrait toujours être capable d'inférer ce qu'il convient de faire d'après la classe de l'erreur.
Tableau A.1, « Codes d'erreur de PostgreSQL » liste tous les codes d'erreurs définis dans PostgreSQL™ 8.1.23. (Certains ne sont pas réellement utilisés mais sont définis par le standard SQL.) Les classes d'erreurs sont aussi affichées. Pour chaque classe d'erreur, il y a un code d'erreur « standard » ayant les trois derniers caractères 000. Ce code est utilisé seulement pour les conditions d'erreurs qui tombent dans la classe mais n'ont pas de code plus spécifique affecté.
Le nom de la condition PL/pgSQL pour chaque code d'erreur est le même que la phrase affichée dans la table, les tirets bas étant substitués aux espaces. Par exemple, le code 22012, DIVISION BY ZERO, a comme nom de condition DIVISION_BY_ZERO. Les noms de condition peuvent être écrit en majuscule ou en minuscule. (Notez que PL/pgSQL ne reconnaît pas les messages d'avertissement, contrairement aux erreurs ; il s'agit des classes 00, 01 et 02.)
