PostgresDB 22025: Invalid Escape Sequence

An escape sequence was invalid.

When encountering the error 22025: Invalid Escape Sequence in Postgres, the user should:

Identify the Query Causing the Error: Review the query that resulted in the error. Pay special attention to the use of escape sequences, specifically within string literals or identifiers.
Check for Incorrect Escape Sequences: PostgreSQL requires that backslashes (\) in string literals be escaped (\\). Ensure that any backslash used in the query is properly escaped. Example correction: Replace '\d' with '\\d'.
Examine String Literals for Proper Formatting: If your query involves string literals that include escape sequences, verify that they are formatted correctly according to PostgreSQL's syntax rules. Incorrectly formatted string literals can trigger this error.
Use StandardConformingStrings Setting: Run the query SHOW standard_conforming_strings; to check if standard-conforming strings are enabled. If the result is off, PostgreSQL interprets backslashes in a non-standard way which could lead to this error. Consider enabling standard-conforming strings by setting standard_conforming_strings = on; in your PostgreSQL configuration file or within your session using SET standard_conforming_strings = ON; for the current session.
Review and Correct Regular Expressions: If the error occurs in a context where regular expressions are used (e.g., REGEXP operations), ensure that the pattern is correctly escaped according to PostgreSQL's regex flavor.
Utilize E'' String Syntax for Escape Strings (if applicable): For string literals that require backslash escapes, use the PostgreSQL E'' syntax to explicitly define escape string constants. Example: Change '\n' to E'\n'.
Consult PostgreSQL Documentation: If the error persists, consult the PostgreSQL documentation regarding escape sequences for your specific version of PostgreSQL, as there might be version-specific behavior or settings affecting how escape sequences are interpreted.
Run Queries in a Safe Environment: Before making changes, especially in a production environment, test your corrected queries in a development or staging environment to ensure they behave as expected.

By following these steps, the user should be able to identify and correct the cause of the 22025: Invalid Escape Sequence error in PostgreSQL.
