PostgreSQL Query Catalog

Project on GitHub
Filter Queries

Found 997 queries.

  • All the queries about database objects contain a subcondition to exclude from the result information about the system catalog.
  • Although the statements use SQL constructs (common table expressions; NOT in subqueries) that could cause performance problems in case of large datasets it shouldn't be a problem in case of relatively small amount of data, which is in the system catalog of a database.
  • Statistics about the catalog content and project home in GitHub that has additional information.

401 Inconsistent naming of columns with BOOLEAN type Find as to whether some columns with the type Boolean start with a prefix ("is", "has", "can", "on") and some do not. Problem detection INFORMATION_SCHEMA+system catalog base tables 2024-01-03 09:54 MIT License View
402 Inconsistent naming of comment columns Find columns of tables that start with the word comment or komment but end differently (excluding numbers). Return result only if there is more than one naming variant of such columns in the database. For instance, a column has the name "comment" but another "comments".

404 Inconsistent referencing to character classes Find as to whether regular expressions use inconsistently references to character classes: [^\s], [^\d], [^\w], [^[:space:]], [^[:digit:]], [^[:word:]] vs [^\S], [^\D], [^\W].

410 Inconsistent use of casting syntax in routines Find as to whether PL/pgSQL routines and SQL routines that do not have SQL-standard body use different syntax for casting (cast function vs :: operator).

411 Inconsistent use of functions and procedures Find as to whether the database has both procedures as well as functions that do not return a value (i.e., return VOID). Such routines are generally used to modify data in the database. The support of procedures was added to PostgreSQL 11.

412 Inconsistent use of gratuitous context in the names of non-foreign key and non-candidate key columns Find the number of names on base table columns that are not a part of a candidate key and a foreign key and that contain the name of the table. Find the number of names on base table columns that are not a part of a candidate key and a foreign key and that do not contain the name of the table. Make sure that table name is used consistently in the column names. Problem detection INFORMATION_SCHEMA+system catalog base tables 2023-10-26 20:25 MIT License View

419 Incorrect characterization of a user-defined routine as an "immutable" routine Find immutable routines that contain SELECT statements from a database (including SELECT .. FOR UPDATE), INSERT, UPDATE, DELETE, or LOCK statement. The DBMS should get a correct background information about the behaviour of a routine. Immutable routines should not have side effects and should also not ask data from a database because it could change over time. Immutable routines cannot lock tables or its specific rows.

420 Incorrect characterization of a user-defined routine as a "stable" routine Find stable routines that contain INSERT, UPDATE, DELETE, SELECT … FOR UPDATE, or LOCK statement. The DBMS should get a correct background information about the behaviour of a routine. Stable routines cannot modify data in a database, lock tables, or its specific rows.
