PHP 8.0: PostgreSQL: Several aliased functions are deprecated
PHP 8 deprecates several function aliases in PostgreSQL extension. These deprecated functions do not appear in the PHP documentation today, and all code that appear to use them are from the PHP 4 era.
However, there are several positive search results on GitHub, which hints of possible deprecation notices in PHP 8.0.
A total of 24 functions are deprecated, all of which were not documented. Last appearance of these functions in documentation appears to be from 2001.

Backwards Compatibility Impact
Deprecated functions above will raise a deprecation notice:
