Improve behavior of libpq's quoting functions (Andres Freund, Tom Lane) § § §
The changes made for CVE-2025-1094 had one serious oversight:
PQescapeLiteral()
and PQescapeIdentifier() failed to honor their
string length parameter, instead always reading to the input
string's trailing null. This resulted in including unwanted text in
the output, if the caller intended to truncate the string via the
length parameter. With very bad luck it could cause a crash due to
reading off the end of memory.
In addition, modify all these quoting functions so that when invalid encoding is detected, an invalid sequence is substituted for just the first byte of the presumed character, not all of it. This reduces the risk of problems if a calling application performs additional processing on the quoted string.
Fix small memory leak in pg_createsubscriber (Ranier Vilela) §
